閉窓の閉窓ロツク装置1. A shoji is attached to a window frame so as to freely swing and open, and the shoji is biased to open a window, and is attached to an open side frame of the shoji and a frame of the window frame corresponding to the frame by a bracket. A swing opening / closing window configured to close a window by winding a wire sequentially wound on a pulley around a drum, in which one of the open side frame of the shoji screen and the frame of the window frame corresponding to the frame. On one side, a locking plate having a locking hole is provided so as to project toward the other side, and on the other side, in the front of the approaching direction of the approaching path where the locking plate enters when the window of the shoji is closed. A claw plate having a fitting portion formed at the tip for fitting into the locking hole of the locking plate,
A mounting body that is swingably supported is mounted between a lock position where the fitting portion approaches the approach path around an axis that is perpendicular to the approach direction and a lock release position that is separated from the upper surface side of the approach path. The swinging force of the claw plate to the lock position, and the attachment body supports the pulley so that the open side frame and the frame can move forward and backward in the approaching direction, and is always attached in the retracting direction. The tension is applied to the wire by winding the wire after closing the window of the shoji to make it possible to move forward against the backward biasing force, and to the bracket of the pulley at the time of the backward movement of the pulley. The claw plate is engaged with an engaging portion of the claw plate to swing the claw plate to the lock release position against the swinging biasing force, and is separated from the engaging portion during the forward movement to move the claw plate to the Actuator that swings to the lock position by swinging biasing force閉窓 locking device rotationally opened and closed windows, characterized in that projecting from the
