<p>An object is to provide a seatbelt retractor and a spindle incorporation method thereof that do not require deformation of a retractor frame, additional components, and additional operating steps even when an additional component having a larger diameter than a spindle, such as a load limiter mechanism, is attached to the spindle. The seatbelt retractor includes a spindle 300 having a recessed portion in a cylindrical surface for retracting a webbing 120, and a retractor frame 240 including two flat plate-shaped side walls 242 that are provided in parallel via an interval A in order to support the spindle 300, each of the two side walls being provided with a circular through hole 244 having a diameter C. An element on a first end of the spindle 300 is contained within a range of a distance D from a deepest portion of the recessed portion 320, and an element on a second end of the spindle 300 is contained within a range of a distance B from the deepest portion of the recessed portion 320. The distance D is smaller than the height C, and the distance B is smaller than the interval A.</p> |
