Patent number: 9493208Abstract: A vehicle prevents interference of a right lamp and a left lamp with a link mechanism without increasing the size of the vehicle in its width direction. A right link side portion of a right lamp is located on the right of a locus along which a link mechanism extends when an upper cross portion turns when looking at the vehicle from the front of an upper middle axis. At least a portion of the right link side portion is located on the left of a right end portion of a body cover, above the upper middle axis, and below an upper end portion of the link mechanism that results when the upper cross portion turns clockwise to a maximum extent relative to a body frame, when looking at the vehicle from the front of the upper middle axis.Type: GrantFiled: June 30, 2014Date of Patent: November 15, 2016Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Kaoru Sasaki, Yosuke Hirayama, Kazuhisa Takano, Toshio Iizuka, Hirotoshi Noguchi
