Patent number: 8371972Abstract: An engine unit includes a crank shaft that receives a driving force of an engine and a moving pulley that is movable in an axial direction. Keyholes are formed on an outer peripheral surface of the crank shaft. Axially extending guide holes are formed on a boss portion of the moving pulley in positions that correspond to the keyholes. Ends of keys are mounted to the keyholes. The guide holes receive therein bases of the keys to guide relative movements of the moving pulley and the crank shaft in an axial direction.Type: GrantFiled: February 8, 2008Date of Patent: February 12, 2013Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Tsuyoshi Sugitani, Mitsukazu Takebe, Atsushi Aoyama

Patent number: 8215439Abstract: In some preferred embodiments, the dry clutch is capable of suppressing transmission of engine rotational fluctuations from the engine to a rider via a vehicle body. In the dry clutch including a driving member (clutch shoe) 66 and a driven member (clutch drum) 62 configured to be engaged with each other and disengaged from each other in a non-lubricating atmosphere to transmit/intercept the motive power of the engine to a drive wheel, a solid lubricant 70 is interposed between the driving member 66 and the driven member 62.Type: GrantFiled: July 24, 2009Date of Patent: July 10, 2012Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Tsuyoshi Sugitani, Mitsukazu Takebe, Fumio Takeda, Atsushi Aoyama, Kotaro Katsuno

Patent number: 7174981Abstract: A first air cleaner box (25) is provided on one side of a rear wheel (4) above a transmission case (9) of a unit-swinging power train unit (1), whereas a second air cleaner box (26) is provided on the other side of the rear wheel (9). Air compartments (40) of the air cleaner boxes (25, 26) are connected to a throttle valve (22) while the air compartments of the air cleaner boxes are made to communicate with each other. The second air cleaner box (26) can be provided by making use of a dead space defined on a side of the rear wheel (4). The capacity of the air compartment (40) can be increased by the first and second air cleaner boxes (25, 26) while preventing the enlargement of the vehicle body, whereby the output of an engine (3) can be increased by increasing the displacement of the engine (3).Type: GrantFiled: June 13, 2003Date of Patent: February 13, 2007Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Tsuyoshi Sugitani, Fumiyasu Sugiyama
