Claims (1)

[Scope of utility model registration request] The output of the motor is transmitted to the rotating shaft via the reduction mechanism,
The worm wheel of the output shaft is rotated via a worm fixed to the rotary shaft, and when the output shaft is locked, the rotary shaft is moved along its length, and the amount of movement is determined by torque. In a torque switch mechanism that operates a motor switch depending on the rotation angle of the shaft, there is a torque lever that swings as the torque shaft rotates, and an opening and closing mechanism in which the operating pin is protruded in opposite directions. a pair of switch operating levers that are normally held down by springs to open and close operating pins of the microswitch, and a pair of switch operating levers that are normally held down by springs to open and close the microswitch operating pins; A torque switch mechanism comprising: a lever pin movably protruding from the lower surface of the torque lever so as to operate one of the switch operating pins in the opening direction and the other in the closing direction.
