ABSTRACT:
A buckle device in which a lock plate is moved by an urging force to be brought into engagement with a tongue plate or, in the state of engagement with the tongue plate, it is moved against the urging force by the operation of a release button to be disengaged from the tongue plate. Stoppers are provided which can be selectively moved during engagement of the tongue plate between inhibition positions, at which they inhibit the above operation of the operation member and also inhibit the lock plate from moving in the direction of movement for disengaging from the tongue plate, and allowance positions at which they allow the above operation of the operation member and also allow the lock plate to disengage from the tongue plate. When maintained at the inhibition position, the stoppers prevent the operation of the operation member and disengagement of the lock plate and the tongue plate.
