Clutch actuator

A clutch actuator comprising:

• a hydraulic pressure generating mechanism configured to operate a clutch to provide a connected state or a cut state by stroking a piston in a cylinder main body to generate a hydraulic pressure and supplying the hydraulic pressure toward a slave cylinder actuating the clutch;
• a motor disposed such that an axial direction of a driving shaft is parallel to an axial direction of the cylinder main body of the hydraulic pressure generating mechanism and configured to generate a rotary driving force for driving the hydraulic pressure generating mechanism to the driving shaft;
• a transmission mechanism configured to transmit the rotary driving force generated in the driving shaft of the motor to a driven member parallel to the driving shaft in the axial direction of the cylinder main body and disposed coaxially with the cylinder main body;
• and
• a conversion mechanism installed coaxially with the piston and configured to convert the rotary driving force transmitted to the driven member into a reciprocal driving force in a stroke direction of the piston;
• and
• an accumulator mechanism connected to a main oil path continuous with a downstream side of the hydraulic pressure generating mechanism,
• wherein the accumulator mechanism extends along a central axis parallel to the axial direction of the driving shaft.
