Description of the Related Art Problems to be Solved by Conventional Techniques and Inventions Conventionally, as a window locking device for a swing opening / closing window of this type, a pair of pinching bodies having a wedge-shaped biting portion opposed to and protruding from a window frame. While fixing one side and swinging the other side so as to oscillate freely and urge in the clamping direction, the shoji has a fitting plate that is fitted between the two clamping bodies, and the fitting plate is fitted when the window is closed. Is inserted between the two pressure plates, the insertion plate is pinched between the two pressure plates so that the biting part bites into the pinching plate to prevent it from coming off, so that the locking plate is locked in the closed window state, and the window opening is performed. At times, it is known that the lock is released by pulling a wire for unlocking, which is different from the one for opening and closing the shoji, to separate the pinching body on the movable side from the fitting plate. With such a conventional device, as the number of times of use increases, the biting part of the pressing member and the pressed surface of the fitting plate become worn. The locking plate may slip out between the two clamping plates even when locking, and the locking function may not be fulfilled.In addition, when the window is opened, the latch of the winding drum may be removed so that the wire for opening and closing the shoji screen can be fed out. In addition to this, it is necessary to pull the wire for unlocking the shoji screen, so that the window opening operation is troublesome.

While the shoji cannot close the window any further, the pulley of the pulley mounting body is supported so that it can move back and forth, so the pulling force acting on the wire causes the pulley to resist the spring elasticity. It is pulled to the forward position, and along with this, the latching claw that has retracted to the lock release position swings to the lock position in the fitting path and latches in the notch of the fitting body, and is then locked by the latch member, etc. Prevents the drum from rotating in the feeding direction and maintains the tensile force of the wire When the sliding door is locked by the hooking claw of the insertion body and the shoji block is locked in the closed window state, and when the drum is allowed to rotate in the feeding direction at the time of opening the window, the pulley supported by the pulley mounting body will have spring elasticity. The wire is paid out to return to the rear position, and along with this, the locking claw swings to the lock release position and is disengaged from the fitting body, so that the lock is released, and the fitting body is pushed by the window opening biasing force. Goes out of the insertion path, and the shoji opens the window while the wire is further unwound from the drum.
