1. A buckle device, comprising:
a buckle main body with which a tongue provided at a webbing to be applied to an occupant is engaged;
a coupling member whose tip side is coupled to the buckle main body;
a winding shaft around which the coupling member is wound from a base end side;
a restricting member configured to restrict drawing-out of the coupling member from the winding shaft, the restricting member being deformed and allowing drawing-out of the coupling member from the winding shaft to allow extension of the buckle main body;
a breaking member configured to restrict drawing-out of the coupling member from the winding shaft, deformation of the breaking member being started to allow drawing-out of the coupling member from the winding shaft when or after the restricting member has started to be deformed, and the breaking member being broken to permit drawing-out of the coupling member from the winding shaft, and
a locking body to which the restricting member and the breaking member are locked.
