Abstract
By driving a first electromagnetic solenoid and a second electromagnetic solenoid, if first cams of a first thrust force amplification mechanism and a second thrust force amplification mechanism are connected to non-rotary members, since second cams are rotated at rotating speeds that are proportional to a vehicle speed V, the relative rotations between the first cam and the second cam increase. Therefore, the first thrust force amplification mechanism and the second thrust force amplification mechanism can be actuated quickly, to thereby switch connection/disconnection states of the first connection/disconnection mechanism and the second connection/disconnection mechanism quickly.
