PURPOSE:To shut a window door completely without overloading a motor. CONSTITUTION:Opening and shutting of a window door 2 mounted to a window frame 1 are operated by a motor. A limit switch 12 detects the state of the window door 2 on occasion just before its complete shutting. As the limit switch 12 is turned on when the window door 2 is put in the state of shutting, driving of the motor is stopped. At the same time, driving of a locking mechanism 13 is started, and thereby the window door 2 is kept under the state of complete shutting. The Locking mechanism 13 is constructed of a solenoid 15 that is driven in pulses, and a lock body 16 that can be engaged with and disengaged from the window door 2 by driving of the solenoid 15 and drives the window door 2 from the state just before the complete shutting to the state of complete shutting and keeps the state of such complete chutting. |
