Webbing take-up device

A webbing take-up device comprising:

• a spool that enables pull-out and take-up of a webbing;
• a rotor disposed opposite from the spool, rotation of the rotor being impeded at a time of emergency;
• a wire of which a proximal end portion is retained at the rotor, at least a distal end portion of the wire being retained at the spool, the wire being disposed between the rotor and the spool, wherein the webbing is pulled out at a time of emergency of a vehicle, the wire being deformed and being wound onto a winding portion of the spool;
• and
• a retreat portion provided at the winding portion, the distal end portion of the wire being disposed at the retreat portion in a case in which the wire is wound onto the winding portion, wherein:
• the winding portion is disposed at a flange of the spool, the flange is formed at one end side, in an axial direction, of the spool, and the winding portion is a rib that is formed along a circumference direction of the spool and that is protruded outwardly, in the axial direction, from the flange, and
• the retreat portion is formed in a sloped shape at one end portion, in the circumference direction, of the rib, and the one end portion is angled, in the axial direction, toward an outer surface of the flange such that a height, in the axial direction, of the retreat portion is tapered.
