PROBLEM TO BE SOLVED: To attach a tension reducer according to variations.SOLUTION: In a webbing take-up device 10, an adaptor 44 is stored in a spring case 36, a fitting hole 46 of the adaptor 44 is exposed by an exposed hole 38A of the spring case 36. For this reason, a spline shaft 108 is fitted into the fitting hole 46 exposed by the exposed hole 38A, so that a tension reducer 70 and a spool 20 are connected to each other by the adaptor 44. This enables the tension reducer 70, aside from a take-up spring 52, to be attached to the webbing take-up device 10 for coping with variations depending on the presence/absence of the tension reducer 70 in the webbing take-up device 10, for example. Thus, the webbing take-up device 10 can be installed with the tension reducer 70 in response to variations. |
