Publication number: 20080158895Abstract: A straddle-type vehicle that reliably inhibits entry of fluid to a tail lamp unit. An extending member protrudes upward from a rear fender and extends in a vehicle width direction. The extending member covers a sealing member of flasher lenses and a tail lamp lens when the motorcycle is viewed from the rear.

Patent number: 6761106Abstract: A compressor includes pistons, each of which is coupled to a swash plate through a pair of shoes. The swash plate rotates integrally with a drive shaft. The shoes convert the rotation of the swash plate to the reciprocation of the piston. A lubricating coating made of copper-based material is formed on parts of the swash plate along which the shoes slide. The copper-based material includes silicon. The shoes smoothly slide on the swash plate, which is coated by the lubricating coating that uses minimum amount of lead.Type: GrantFiled: April 18, 2002Date of Patent: July 13, 2004Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Manabu Sugiura, Takahiro Sugioka, Akira Onoda, Tomohiro Murakami, Shino Okubo

Patent number: 6666128Abstract: A swash plate type variable displacement compressor has a housing, a drive shaft, a swash plate and a piston. The housing includes a cylinder block, a front housing, and a rear housing. The drive shaft is rotatably supported by the housing. The swash plate is connected to the drive shaft, and is integrally rotatable with the drive shaft and tiltable relative to the drive shaft. The piston engages with the swash plate through a pair of shoes. Rotation of the drive shaft is converted to reciprocation of the piston through the swash plate and the shoes, and the displacement of the compressor is adjusted by varying the inclination angle of the swash plate with respect to the axis of the drive shaft. The swash plate includes a base member made of copper series and a sliding layer coating a sliding surface of the base member with respect to the shoes.Type: GrantFiled: April 18, 2002Date of Patent: December 23, 2003Assignee: Kabushiki Kaisha Toyoto JidoshokkiInventors: Manabu Sugiura, Takayuki Kato, Hideki Mizutani, Takahiro Sugioka, Akira Onoda, Tomohiro Murakami, Shino Okubo

The shoe preferably comprises a main body, a metallic hard layer at least partially disposed on the main body and an anti-friction layer at least partially disposed on the metallic hard layer. The main body preferably comprises a spherical surface portion and a substantially flat surface portion and comprises aluminum. The metallic hard layer preferably has a hardness of at least HV 300 based upon the Vickers hardness scale and is disposed on at least one of the spherical surface portion and the substantially flat surface portion.
