| 20090126526 | Operation Lever Structure - An operation lever structure wherein an operation lever is pulled toward a left handle to cause a link to swing-move to thereby operate an operation cable. The operation lever structure is configured so that each of inside and outside rollers are provided to an opposite end of the link. Inside and outside guide holes for movably supporting the inside and outside rollers are formed in each of a pair of inside and outside side walls. A discharge opening is formed in a bottom part of the operation lever for discharging a foreign matter that has entered the operation lever. | 05-21-2009 |
| 20090127009 | HANDLE STRUCTURE OF WALK-BEHIND WORKING MACHINE - A handle structure of a walk-behind working machine includes: a handle having left and right raised portions extending upward from a handle frame and a cross portion interconnecting the left and right raised portions; and a main clutch lever shiftable from a clutch-OFF position to a clutch-ON position by being pivoted into pressed abutment against the cross portion. The main clutch lever is constructed in such a manner that, when the main clutch lever is in abutment against the cross portion, a space for allowing a human operator to grip the left and right raised portions is secured between the left and right raised portions and the main clutch lever. | 05-21-2009 |
| 20090288514 | TRANSMISSION - A transmission has a movable transmission part movably connected to a fixed transmission part via a shaft to undergo pivotal movement relative to the fixed transmission part about an axis of the shaft. Each of the transmission parts has a hollow cylindrical connecting portion through which the shaft extends. One of the connecting portion of the movable transmission part and the connecting portion of the fixed transmission part is received in the other of the connecting portions with a single seal member disposed therebetween so that an internal space of the fixed transmission part and an internal space of the movable transmission part communicate with each other to thereby form a single hermetically-sealed space for holding therein a lubricating oil. | 11-26-2009 |
| 20110083328 | BUSH CUTTER - Driving power is transmitted to an output shaft, via driving and driven bevel gears, to a cutter blade. A gearbox supports the output shaft via first and second bearings. The second bearing is engaged by an engaging member to be prevented from axial movement, toward the blade, relative to the gearbox and supports the output shaft near the cutter blade. The output shaft is connected to the driven bevel gear such that it is prevented from rotation relative to the driven bevel gear but allowed to move axially. When the engaged state, by the engaging member, of the second bearing is canceled, the shaft is allowed to axially move toward the cutter blade until the shaft becomes rotatable relative to the driven bevel gear, at the same time of which a retaining stopper prevents the shaft from further axial movement. | 04-14-2011 |

| 20080237953 | Vibration damping mounting assembly - A vibration damping mount assembly having a vibration damping mount main body and a tubular bracket. The tubular bracket is made of lightweight material composed of non-ferric metal or synthetic resin, and has an inside peripheral face including an upper tapered face and a lower tapered face that gradually expand in diameter towards openings at either axial end from an axially medial section. A flanged portion of a second mounting member is axially juxtaposed against an open end of the upper tapered face, while the lower tapered face is pressed against a rubber fitting, with the lower tapered face locked in contact against an annular mating face of the rubber fitting thereby providing dislodging of the vibration damping mount main body from the tubular bracket. | 10-02-2008 |
| 20080284076 | CYLINDRICAL VIBRATION ISOLATING DEVICE - The object of the present invention is to prevent damages of a vibration isolating rubber and cracks in a welded portion of a sub-frame when press-fitting a sub-frame mount. | 11-20-2008 |
| 20090008845 | Pneumatic actuator for vibration damping device and vibration damping device using the same - A pneumatic actuator for use in a vibration damping device comprising: a base housing; an elastic wall member being fastened fluid-tightly to the base housing to form a working air chamber therebetween; and an urging member positioned within the working air chamber for exerting urging force on an output portion provided to the elastic wall member, such that the output portion is actuated to undergo displacement in opposition to the urging member through change in an air pressure in the working air chamber from an outside. At least one of opposing faces of the base housing and the elastic wall member on the working air chamber side thereof has a plurality of rib portions which extend from an inner circumferential side thereof towards an outer circumferential side thereof. A vibration damping device equipped with the pneumatic actuator is also disclosed. | 01-08-2009 |
| 20090038896 | Fluid filled type vibration damping device - A fluid filled type vibration damping device having an orifice passage formed in a partition member to connect a pressure receiving chamber and an equilibrium chamber, wherein a first end section of the orifice passage extends in along a plane of the partition member, and a communication hole is formed to bend at a right angle from the first end of the orifice passage and open towards the pressure receiving chamber to form a dead water region by orthogonal wall faces of a terminal end face and a bottom face of the orifice passage in a connecting corner section of the orifice passage with the communication hole. A shunt hole of smaller cross-sectional area than the orifice passage and the communication hole is formed in a bottom wall so that the pressure receiving chamber and the equilibrium chamber communicate through the shunt hole in the dead water region. | 02-12-2009 |
| 20110115258 | MOUNTING OF SUBFRAME - In a structure for mounting a subframe, located under a vehicle body, to the vehicle body via an elastic assembly, the elastic assembly includes: a first mounting member located under the vehicle body and over the subframe; a second mounting member located immediately above the first mounting member; and an elastic member disposed between the first and second mounting members. The first mounting member is mounted to the vehicle body, while the second mounting member is mounted to the subframe. | 05-19-2011 |
