PROBLEM TO BE SOLVED: To stably transmit-receive an obstacle detection signal by a radio system of an electromagnetic wave.SOLUTION: In a state of receiving a disturbance radio wave signal, operation in closing time of an opening-closing body is operated for closing in a different mode from ordinary closing operation and/or operation in opening time is operated for closing in a different mode from ordinary opening operation. The opening-closing body is operated for closing only when an operator operates a closing operator for push-cutting in the vicinity of an opening part. When a disaster prevention signal is inputted when the opening-closing body stops, the closing operation and stopping operation are alternately repeated after a predetermined time passes or the closing operation, the stopping operation and avoidance operation (ascent operation) are repeated after the predetermined time passes, and dead weight closing operation is executed thereby. When the opening-closing body is in the closing operation, the closing operation of the opening-closing body is stopped once, and the closing operation and the stopping operation are alternately repeated after the predetermined time passes from stopping time, or the closing operation, the stopping operation and the avoidance operation (the ascent operation) are repeated after the predetermined time passes, and the dead weight closing operation is executed thereby. |
