Patent abstract
In a buckle device, when a belt starts to be allowed to be drawn, a fracture portion is deformed by a side surface of a connection hole of a spool, so that the fracture portion allows a rotation of the spool and allows drawing of the belt. Then, the fracture portion is fractured by the side surface of the connection hole. Therefore, a drawing allowance load of the belt when the belt starts to be allowed to be drawn can be increased.
