Abstract: Abrasion of a V-belt in a belt type continuously variable transmission accommodated in an engine unit of a motorcycle is suppressed. A V-belt wound around and contacting a primary sheave and a secondary sheave 72 is at least partially formed from a resin. A plurality of grooves aligned at a predetermined pitch in a radial direction are formed on sheave surfaces of the primary and secondary sheaves. The average pitch P(mm) of the grooves is P≦−0.08K×10−3+0.18, where K(Hv) indicates surface hardness of the sheave surfaces.

Abstract: An engine unit for a motorcycle that efficiently supplies lubricating oil to a clutch mechanism includes a connecting rod connected to a crank shaft, an oil pump, a clutch shaft having a clutch shaft body and a centrifugal type clutch, and a reduction mechanism having a reduction shaft in parallel to the crank shaft. The oil pump supplies lubricating oil to a connection of the crank shaft and the connecting rod. The clutch shaft body is arranged in parallel to the crank shaft. The clutch shaft body is closer to the crank shaft than is the reduction shaft. Lubricating oil supplied to the connection to scatter is led to the clutch shaft.

Abstract: To enhance the durability of the V-shaped belt by allowing the strength and the heat-radiating property of the resin blocks to stand together at high levels in the V-shaped belt, which has a plurality of resin blocks and endless connecting members connecting the resin blocks. The V-shaped belt includes a plurality of resin blocks arranged in a direction and an endless connecting member that is impacted into the resin blocks and that extends in the arrangement direction of the resin blocks. Depressions are longitudinally and vertically formed in the upside and downside of the front surface and the rear surface of each resin block. The depressions are separated from the connecting member and are also separated from the lateral surfaces of the resin block.
