油圧ロータリアクチユエータ。 A hydraulic rotary actuator that extracts the rotational power of a hydraulic motor as output torque through a reduction mechanism such as a harmonic drive type, and has teeth on the front surface of the input shaft of the hydraulic motor and a braking armature provided adjacent to the input shaft of the hydraulic motor. A face gear with a relatively shallow angle is formed so that braking is applied by meshing both face gears, and the armature is connected to a field having a built-in brake release coil that moves the armature backward to disengage the face gear. A hydraulic rotary actuator characterized by having a support member that supports the armature so as to be movable back and forth, and a braking spring that presses the armature toward the input shaft so as to apply braking force within a preset range. .
