Claims

[Scope of utility model registration request]

A buckling device in which the lock member is moved by the urging force of the urging means to engage the tongue plate, and from the tongue plate engaged state, the lock member is moved by the movement operation of the release operation member and is disengaged from the tongue plate. A lever is provided between the locking member and the disengagement operating member, and is moved forward and backward on the locus of movement of the locking member in the tongue plate disengagement direction. The lever is rotatably supported by the release operating member at a position offset from the center of rotation, and the bearing hole has a shaft that positions the lever on the locus of movement of the lock member in the tongue plate release direction when the tongue plate is engaged. The first bearing hole is communicated with the first bearing hole to lock the lever via the release operation member when the release operation member is operated to move from the tongue plate engagement state. A long hole-shaped second bearing hole for swinging in the exiting direction is communicated with the first bearing hole to lock the lever when the lever receives swinging force via the locking member while the tongue plate is engaged. A third bearing hole in the form of an elongated hole is provided for swinging the member in the direction of exit from the movement locus in the tongue plate dissociation direction, and the longitudinal dimension of the third bearing hole is longer than the longitudinal dimension of the second bearing hole. When the lever is shortened and the tongue plate is engaged and receives a swinging force via the lock member in a direction in which the lock member moves away from the locus of movement in the tongue plate disassembly direction, the lever swings the lock member in the tongue plate disengagement direction. A buckling device that is characterized by not leaving the moving trajectory.
