Abstract
A buckle apparatus comprises a buckle body into which a tongue plate is inserted, and a lock plate with which the tongue plate is engaged and locked. The buckle body is provided with an opening through which a portion of the lock plate is passed in a condition of the tongue plate locked to the lock plate, so that when a load larger than a predetermined value is applied in a direction of withdrawal of the tongue plate in such locked condition, at least a portion of the lock plate is moved in the tongue plate withdrawal direction. Such portion of the lock plate is provided with a projection which is adapted to be brought into engagement with an edge of the opening by the movement of such portion, thereby inhibiting the movement of the lock plate in a direction to release the tongue plate-locked condition. Therefore, even if a load larger than a predetermined value is applied to the tongue plate in the locked condition, the tongue plate cannot be disengaged from the buckle apparatus.
