<p><P>PROBLEM TO BE SOLVED: To provide a compact clutch actuator, in a transmission mechanism including: first and second transmissions different in gear ratio; a first clutch connecting/disconnecting between an input gear and the first transmission; a second clutch connecting/disconnecting between the input gear and the second transmission; a first drive piston operating the first clutch; a second drive piston operating the second clutch; a cam body driven by a motor, and pressing and driving one of the first and second drive pistons; a first driven piston connecting/disconnecting the first clutch; and a second driven piston connecting/disconnecting the second clutch. <P>SOLUTION: The clutch actuator includes: a rotational shaft rotatably journaling the cam body; an assist mechanism assisting the cam body along with rotation of the rotational shaft; and a load operating point B to which a load by the assist mechanism is transmitted to the rotational shaft. At a neutral position of the cam body, the load operating point B and the center C of the rotational shaft are disposed on a line in a load operating direction of the assist mechanism. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
