全装置。 It consists of a door body fitted in a guide rail, a connecting member for suspending the door body, and a winding shaft that winds and unwinds the connecting member by rotating the electric opening/closing machine in forward and reverse directions, and operates the electric opening/closing machine. In an electrically operated overhead door that opens and closes by raising and lowering the door body, a safety switch is attached to the door body and sends a stop signal to the electric opening/closing machine by actuation of an actuator, and a safety switch is rotatably attached to the door body. A wire hanging fixture is attached to the wire and has a hanging base on one side that connects the above-mentioned connecting member and a contact part that presses the actuator of the above-mentioned safety switch on the other side. A safety device for an electrically operated overhead door, comprising a biasing member that rotates a contact portion of a hanging fitting toward an actuator of the safety switch.
