Engine unit and straddle type vehicle |
摘要 |
In an engine unit of a straddle type vehicle, a V-belt-type continuously variable transmission (CVT) has a secondary sheave shaft 62 that rotates with a clutch housing of a centrifugal clutch. The secondary sheave shaft is supported in a cantilever fashion via two bearings. The engine unit has a gear that rotates with a clutch boss. Cage-and-roller needle bearings, which are a type of needle bearing, are inserted between the secondary sheave shaft and the gear. In this manner, without enlarging the engine unit, abrasions and deterioration of a bearing inserted between a rotational shaft supported in a cantilever fashion and a body of rotation are prevented. |
