Therefore, if the circular through hole of the retractor frame 12 is enlarged, further additional components are required, such as bearings at the ends 16a and 16b of the mandrel, so that the circular through hole 14 of the retractor frame 12 supports the mandrel. 16 ends, therefore, also create cost issues

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.
Description
technical field [0001] The invention relates to a retractor for a safety belt and a method for assembling a mandrel of the retractor for a safety belt. technical background [0002] Seat belt devices have been installed on the seats of vehicles all the time. When a large deceleration such as sudden braking or collision acts on the vehicle in an emergency, the driver and occupant are restrained, and the driver and occupant are restrained from flying forward due to inertial force. The seat belt device includes a retractor arranged behind the seat back or inside the seat back. The retractor can freely release the seat belt, which is the webbing that binds the driver and occupant, in an emergency, and at the same time, take up the webbing by rotating force. Therefore, even if the occupant is active at ordinary times, the webbing will not be loose, but will always be close to the body of the occupant. [0003] In fact, it is the mandrel arranged on the retractor that takes up t...
