Abstract

A clutch engaging and disengaging apparatus is provided with a motor , a motion converting mechanism that converts the rotational motion of the motor into linear motion, a load storing mechanism that stores a load when the motion converting mechanism moves linearly in one direction and releases the stored load when the motion converting mechanism moves linearly in the opposite direction, and a hydraulic mechanism that uses the linear motion of the motion converting mechanism to produce hydraulic pressure and engage or disengage the clutch. The load storing mechanism has an assist spring that is coupled to the motion converting mechanism and can extend and contract in response to the linear motion of the motion converting mechanism and a spring cover that supports an axially facing end part of the assist spring
