る。 In the embodiment described above, the drive chain 31 is rotated by operating the motor 33, and the actuation chain 22 with which the drive chain 31 is engaged is rotated. The reaction force applied to the movable body 24 at this time is received by the compression spring 28. When a large load is generated on the working chain 22 side for some reason and the working chain 22 cannot rotate smoothly, a large reaction force is generated in the movable body 24 in opposition to the load, and the movable body 24 will move against the elasticity of the compression spring 28. This movement is manifested in the movement of the striker 45, and the cam surface 46 acts on the cam roller 48, causing the operating rod 47 of the limit switch 49 to swing from the solid line to the imaginary line in FIG. When the movable body 24 moves by a certain amount or more, the limit switch 49 detects and operates.
Upon this detection, the motor 33 is automatically stopped.
