Claims

[Scope of utility model registration request]

This is used when a plurality of seat belt devices each having a tongue plate and a buckle are arranged in close proximity, and each buckle is provided with a locking member, and when the tongue plate is inserted, the locking member engages with the tongue plate. A buckle device having a structure in which the tongue plate insertion opening is wide in the tongue plate thickness direction and the length in the tongue plate insertion direction from the tongue plate insertion opening to the locking member at the tongue plate engagement position is long. a first buckle; and a second buckle, in which the tongue plate insertion opening is narrow in the tongue plate thickness direction and the length in the tongue plate insertion direction from the tongue plate insertion opening to the locking member at the tongue plate engagement position is short. The lock member can be inserted into the first buckle up to a position where it is engaged, but at least a portion thereof is thickened so that it cannot be inserted into the tongue plate insertion opening of the second buckle, so that the lock member cannot be inserted into the second buckle. A first tongue plate that cannot be inserted into a position where the member is engaged, and a second tongue plate which can be inserted into a position where a lock member is engaged, but there is no insertion into the second buckle. The length from the base of the insertion part to the engaging part with the lock member is made shorter than the length in the tongue plate insertion direction from the tongue plate insertion opening of the first buckle to the lock member, so that the lock member is not inserted into the first buckle. A buckle device comprising: a second tongue plate that cannot be inserted into the engaged position.
