20120177310 | CRANKSHAFT SUPPORT STRUCTURE - A crankshaft support structure including a bushing which allows a bearing member to be held firmly on a crankcase, the bearing member supporting a crankshaft rotatably on the crankcase wherein the holding strength of the crankcase for the bushing needs to be increased. The crankcase needs to have a lighter weight and the thermal expansion of the crankcase needs to be prevented from affecting a bearing. An outer circumferential surface of the bushing which is insert-cast in the crankcase has a cylindrical shape, and many small protrusions each having a constricted portion are formed on the outer circumferential surface. Accordingly, the holding strength of the crankcase for the bushing is increased, allowing a small thickness of a bushing holding portion of the crankcase. | 07-12-2012 |
20120199087 | ROCKER ARM STRUCTURE - A rocker arm arranged between a camshaft and a valve which opens/closes an intake port or an exhaust port. A rolling bearing for supporting a support hole formed in a rocker arm is of a type of bearing wherein a plurality of needles are mounted on an inner side of an outer peripheral shell, and the outer peripheral shell is fixed to the support hole, the cam follower includes an outer ring which is supported on a periphery of a cam follower shaft which is held by a pair of left and right arm portions of the rocker arm by way of a plurality of rollers, a position of the outer ring and a position of the rollers in the lateral direction are restricted by the arm portion, and an outer diameter of the outer ring is set equal to or less than an inner diameter of the support hole. | 08-09-2012 |
20120216984 | RADIATOR COOLING STRUCTURE FOR WATER-COOLED POWER UNIT - Disclosed is a radiator cooling structure for cooling a radiator of a water-cooled power unit mounted on a small vehicle and disposed on a laterally outer side of the small vehicle, which radiator cooling structure improves the efficiency of cooling an internal combustion engine by using a head wind. The radiator is provided with a radiator cover having a louver for guiding cooling air to the radiator. The louver is formed such that a rear part thereof is more protruded laterally outward than a front part thereof. The louver of the radiator cover has parallel slats tilting forward, and a lower body cover is provided with a cooling air intake opening capable of guiding a head wind toward the louver positioned obliquely above and rearward of the cooling air intake opening. | 08-30-2012 |
20120289370 | COOLING AIR INTAKE STRUCTURE FOR V-BELT DRIVE CONTINUOUSLY VARIABLE TRANSMISSION - Disclosed is a cooling air intake structure for a V-belt drive continuously variable transmission, which is disposed beside the rear wheel of a small vehicle and which does not permit muddy water and dust to enter therein. A cooling air inlet through which cooling air is taken in is formed at a position beside a transmission case and above a cooling fan side opening formed in the transmission case opposite to a drive pulley. A cooling air passage extending from the cooling air inlet to the side opening is formed so as to surround the side opening. Cooling air taken in through the cooling air inlet is guided so as to flow upward first and then flows downward along a U-shaped cooling air passage to the side opening of the transmission case beside the cooling fan. | 11-15-2012 |

20140334172 | Vehicle Lighting Device - A vehicle lighting device according to embodiments includes a light emitting unit, a holding unit, a light guide, a cover and an attachment unit. The light emitting unit has one or more light emitting elements. The holding unit holds the light emitting unit. The light guide guides light emitted from the light emitting unit and emits the light from a tip which is an opposite side to the light emitting unit side. The cover has a first fixation unit to be fixed to the holding unit and a second fixation unit which has a diameter smaller than that of the first fixation unit and internally fixes the light guide thereto in a state of exposing the tip. The attachment unit attaches the vehicle lighting device to a light emitting object (lamp) to which the light guided from the light guide is emitted, and is formed in the second fixation unit. | 11-13-2014 |
20140369049 | Luminaire - According to one embodiment, there is provided a luminaire including a light-emitting element and a cover provided on an irradiation side of the light-emitting element. The cover includes a first light transmitting section provided on the center side of the cover and a second light transmitting section provided at the peripheral edge of the first light transmitting section and having light transmittance higher than the light transmittance of the first light transmitting section. | 12-18-2014 |
20150062942 | Lighting Device - According to an embodiment, a lighting device includes: a light emitting section that has a light emitting element and a switch for controlling a lighting state of the light emitting element; a housing that stores the light emitting section and of which one end section is open; a cover that covers the opening of the housing and has translucency; and a frame that is provided between the housing and the cover. The frame includes an edge section that presents a frame shape and a holding section of which one end is provided in the edge section and the other end protrudes from the edge section, and which holds an operation section operating the switch and is exposed from the cover. | 03-05-2015 |
