|20130248044||VENT DUCT - A vent duct having an inner fluid flow passage includes a bent portion formed to a duct body portion at which the fluid flow passage is bent, and a protruded portion formed on a downstream side of the bent portion so as to protrude from an inner peripheral surface portion toward an axial center of the fluid flow passage, wherein the protruded portion includes an upstream side end portion formed to be gently continuous to the inner peripheral surface portion of a downstream side portion of the bent portion, a body portion extending from the upstream side end portion toward the downstream side portion along the fluid flow passage, and a downstream side end portion along the fluid flow passage to be continuous to the body, the downstream side end portion of the protruded portion being formed to be perpendicular to the inner peripheral surface portion.||09-26-2013|
|20130199486||INTAKE MANIFOLD - An intake manifold is provided with a chamber member provided with an exhaust port and a chamber formed therein, a port member provided with an intake groove forming a ventilation passage bent so as to be communicated with the exhaust port and the chamber of the chamber member when the chamber member and the port member are welded together, and a cover member that covers the port member from a side opposite to the welded side between the chamber member and the port member. The intake groove has an outer wall surface opposing to the chamber member is formed with a reinforcing member so as to protrude from at least one of the port member side or chamber member side toward another one thereof, and the reinforcing member extends along an extending direction of the intake groove, the reinforcing member is welded to another reinforcing member protruding from another outer wall surface of the port member and chamber member, or from the port member and the chamber member.||08-08-2013|
|20130147126||SEAL MEMBER - A seal member has a ring shape which is assembled in a portion between a tubular member to be inserted into and fixed to a mount hole formed to a head cover of an internal combustion engine and a peripheral wall portion of the mount hole. The seal member is provided with an axial-direction seal portion formed to axial one end portion of the seal member, and a diameter-direction seal portion formed to another one end of the seal member. A fixing member configured to fix movement in a diameter direction of the seal member between the axial-direction seal portion and the diameter-direction thereof is formed along a peripheral wall portion of the mount hole.||06-13-2013|
|20120021179||INTAKE UNIT - An intake unit includes a first member, a second member and a third member, which are manufactured separately and then welded together under application of pressure, wherein a welded portion between the first member and the second member and a welded portion between the second member and the third member are positioned in an overlapped manner, and a first jig receiving surface is formed to the overlapped welded portion between the welded portion between the second member and the first member and the welded portion between the second member and the third member so as to avoid the overlapping therewith.||01-26-2012|
|20110284453||OIL FILTER FOR AUTOMATIC TRANSMISSION - An oil filter for an automatic transmission includes a housing which is composed of a case having an opened end portion and a cover covering the opened end of the case, the case being formed with a flow-in port and the cover being formed with a flow-out port, a filter element dividing an interior of the housing into a dust side section positioned on the flow-in port side and a clean side section positioned in the flow-out port side, the filter element including a first filter to which a flow-in hole continuous to the flow-in port is formed and a second filter opposing to the first filter, and a flow passage ensuring unit disposed between the first filter and the second filter for defining a predetermined gap therebetween.||11-24-2011|
|20100257828||AIR CLEANER - An air cleaner is provided with: a case in which a filter element is housed and which has an opening; a cover that covers the opening of the case to be opened or closed; a hinge structure having a hinge formed to the cover and a hinge receiver formed to the case to be engaged with the hinge in a detachable manner such that the cover is pivotal around the hinge with respect to the case; and an engagement maintaining mechanism provided to side surfaces of the case and the cover so as to maintain the engagement between the case and the cover in a range in which the cover closes the case and in a range in which the cover is opened by a predetermined angle.||10-14-2010|
|20100224439||INTAKE SOUND ADJUSTING DEVICE - An intake sound adjusting device includes an intake passage, a tubular branch passage branched from the intake passage, and an oscillating member disposed within the branch passage, in which the oscillating member has an oscillating portion disposed so as to close an interior of the branch passage and a controlling portion extending from the oscillating portion in a direction along an extending direction of the branch passage.||09-09-2010|
|20100018589||OIL PAN - An oil pan includes a bottom portion, a side wall portion standing upward form an edge portion of the bottom portion, a cylindrical lubricating oil amount adjusting wall structure standing upward from substantially the central portion of the bottom portion and formed, to an inner peripheral portion thereof, with a lubricating oil amount adjusting passage which communicates with an external portion, the lubricating oil amount adjusting wall having a lubricating oil drain port formed to a lower portion thereof, a cylindrical lubricating oil adjusting plug assembled detachably to the lubricating oil amount adjusting passage so that the lubricating oil adjusting plug closes the lubricating oil drain port, the lubricating oil amount adjusting plug being formed with a communication port communicating with the lubricating oil amount adjusting passage, and a drain plug fitted detachably to the communication port.||01-28-2010|
