フトフオークを示す。 To explain this with reference to the illustrated embodiment, 1 is an engine, 2 is a crankcase, a crankshaft 3 inside the case 2 is placed horizontally with respect to the direction of movement of the vehicle body, and a transmission is connected to the shaft 3 via a clutch outer 4. shaft 3
A gear shift spindle 7 of a gear shift mechanism 6 which is arranged behind the transmission mechanism 5 and which shifts each gear on the main shaft 5a and countershaft 5b of the transmission 5, and a gear starter spindle 9 of the gear starter mechanism 8 which is to be interlocked with the transmission 5. Bearings 10 that support the left and right sides of the case 2 are provided at positions that bisect the case 2. Note that the bearing 10 is attached to each spindle 7,
One end of each spindle 9 is directly inserted and supported, and the other end of each spindle 7, 9 is supported by the case 2, respectively, and the spindle 9 is supported via a bearing 11. The shift gear mechanism 6, that is, the shift drum 6a that is interlocked with the arm 7a of the shift spindle 7, and the drive ratchet 8a and starter pinion 8b that are attached to the kick starter mechanism 8, that is, the kick starter spindle 9, are on the same plane when viewed from the side. placed above. In the figure, 12 indicates a cam plate provided on the shift drum 6a, and 13 indicates a shift fork.

A bearing 10 is provided to support the left and right sides of the crankcase, and the gear shift mechanism 6 and the hard starter mechanism 8 are arranged on the same plane on both sides of the bearing 10 when viewed from the lateral direction. In addition, the gear shift spindle and the gear starter spindle can be mounted without increasing the mounting width, and the crankcase can be made smaller and lighter.
