Power unit for vehicle and vehicle therewith

摘要

A power unit for a vehicle has a clutch actuator and an operating force transmission mechanism 15 which transmits drive force of the clutch actuator to a clutch. The clutch actuator and the operating force transmission mechanism 15 are arranged at a right end portion within a casing of the power unit. A drive shaft of the clutch actuator extends in the vertical direction. The operating force transmission mechanism 15 has a worm shaft 16 which is disposed at the drive shaft of the clutch actuator, a first solid of revolution 19 including a worm wheel portion 19a which engages with the worm shaft 16, a second solid of revolution 24 which engages with a gear portion 19c of the first solid of revolution 19 and a ball cam 20 which converts torque of the second solid of revolution 24 into force of axial direction of a slide shaft of the clutch.
