PROBLEM TO BE SOLVED: To ease the manual opening and closing operations by applying motor brake in a period of time from the opening and closing operations to the start of operation of a slide door motor to restrain it and turning off a magnet clutch when it is at a fully close position. SOLUTION: A slide door motor 42 and a magnet clutch 43 are stored inside a motor part 3, and a lock connected with a striker and a lock out actuator 13 are stored inside a slide door. A controller 21 causes the slide door motor 42 to generate electrical brake, releases motor brake after turning on the magnet clutch 43, and releases a lock condition. After that, it drives the slide door in the direction of opening. When a door switch is fully closed continuously, the slide door motor 42 is stopped, and the magnet clutch 43 is turned off. When the slide door stops during the opening and closing operations and is at a fully open position, the magnet clutch 43 is connected. Consequently, it is possible to prevent its travel due to its self-weight securely. |
