Abstract

The present invention provides a power unit for a vehicle having a crankshaft rotatably supported to a crankcase while having its axis set along the front-rear direction of said vehicle in the power transmission path for transmitting a rotational drive force of said crankshaft to a drive wheel, and a clutch is provided in said power transmission path for switching connection and disconnection of the transmission of power. A clutch actuator(96) that is provided on the engine body (11) is mounted on said engine body for controlling the switching between an engaged condition and disengaged condition of said clutch, and the length from the front to the back of the engine and the vehicle can be prevented from being longer by using side arranging method of the clutch actuator.

Description

technical field [0001] The present invention relates to a power plant for a vehicle, in which a crankshaft has an axis line along the front-rear direction of the vehicle and is rotatably supported by a crankcase, and in the middle of a power transmission path that transmits rotational power of the crankshaft to drive wheels, An on / off clutch capable of switching power transmission is provided, and a clutch actuator for controlling on / off switching of the above-mentioned clutch is installed on the engine body including the above-mentioned crankcase. Background technique [0002] Such a power plant for a vehicle is disclosed in, for example, Patent Document 1 or the like. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 11-222043 [0004] However, in the vehicle power unit disclosed in the aforementioned Patent Document 1, the clutch actuator is arranged at the rearmost part of the engine body, and the front-rear length of the engine is increased, so that...
