Abstract

See full text

A hydraulic actuator includes a tool unit (10) having a tool that operates by pressurized oil generated by a hydraulic pump (40), a driving unit (60) that generates a rotation torque, and a torque transmission coupler (70) to one end of which the tool unit (10) is detachably attachable and to other end of which the driving unit (60) is detachably attachable and that transmits the rotation torque generated by the driving unit (60) to a rotatable member (41) of the tool unit (10). The torque transmission coupler (70) includes a flexible rod-like shaft (74) and a flexible cover (72) that surrounds an outer peripheral surface of the shaft. The torque transmission coupler (70) is bendable as the shaft (74) and the cover (72) have flexibility.
