1. A buckle device comprising:
a buckle body configured to engage with a tongue provided at a webbing worn by an occupant;
a coupling member coupled to the buckle body;
a take-up shaft onto which the coupling member is wound, that is coupled to the buckle body via the coupling member, that is configured to limit pull-out of the coupling member, and that is configured to permit pull-out of the coupling member at a pull-out permitting load or greater so as to permit extending of the buckle body; and
a slide section across which the coupling member is configured to slide,
wherein, when pull-out of the coupling member from the take-up shaft is permitted, a combined radius of the coupling member and the take-up shaft at a pull-out position of the coupling member from the take-up shaft becomes smaller so that a slide resistance of the coupling member with respect to the slide section becomes smaller.
