The dead bolt 120 has a rack gear formed on the upper surface, and a smoother (roller) 122 is attached to the end facing the strike 206 to smoothly enter and retract the strike. The spring 124 is biased toward the strike side. The L-shaped arm plate 126 is pin-coupled to the dead bolt 120 at the loose hole 128 at the upper end thereof, and is pin-coupled to the push-down stay 130 at the loose hole 128 at the lower end, and is rotated clockwise about the rotation axis of the L-shaped center. It can rotate counterclockwise.
[0013]
As will be described later, when the pusher is pushed, the push-down stay 130 is pulled down by the pull-down hardware engaged with the pusher-side pull-down hardware hook 132 and rotates the L-shaped arm plate 126 in the clockwise direction. Thus, the dead bolt 120 is driven rightward against the coil spring 124. At the time of locking, the magnet trigger 110 is urged counterclockwise and the clutch gear 118 is disengaged from the projection of the magnet trigger. As a result, the dead bolt 120 is driven to the left by the coil spring 124, and the L-shaped arm plate 126 is The push-down stay 130 is pulled upward by rotating counterclockwise.
