ツター開閉機における手動装置。 A brake shoe 2 fixed to an electric motor shaft 1 and a brake drum 4 fixed to a brake shaft 5 are arranged facing each other so as to be able to come into contact with each other, and in a normal state, a brake spring 1 is provided on the back of the brake drum 4.
6, the brake drum 4 is pressed onto the brake shoe 2, and the chain wheel 6 is rotatably fitted to the brake drum 4 fixed to one end of the brake shaft 5, so that the outer peripheral surface of the chain wheel 6 and A roller 23 and a lock pin 26 are attached to relative positions on the outer peripheral surface of the brake drum 4 so as to be able to move toward and away from each other, and the lock pin 26 is pressed against the brake drum 4 to lock it, and the chain wheel 6 is rotated by pulling the chain 7. This is a manual electric shutter opening/closing machine in which the roller 23 is separated from the chain wheel 6 and the actuating plate 24 is pushed down to lower the lock pin 26 that is in pressure contact with the brake drum 4 to release the lock on the brake drum 4. Device.
