チユエータ。 The hydraulic air servo is equipped with a variable resistance type stroke sensor, and the brush holder of the stroke sensor and the power piston of the hydraulic air servo are linked via a rod, and the amount of movement of the power piston is detected by the stroke sensor. In the clutch actuator, a discontinuity is formed at at least one place in the power transmission system from the power piston to the brush holder, and when the hydraulic air servo is inactive, the power transmission system from the power piston to the brush holder is discontinuous. An actuator for a clutch, characterized in that vibrations transmitted to the holder are blocked by the discontinuous portion.
