PROBLEM TO BE SOLVED: To obtain a webbing winder which can continue increase in an absorption amount of a torque of a spool in association with increase in a rotation amount of the spool.SOLUTION: In a webbing winder 10, a rotary member 44 is connected to a spool 18 at a time of vehicle emergency, and the rotary member 44 is rotated together with the spool 18. Consequently, a part of a torque of the spool 18 can be continuously absorbed by a friction force generated between a slide contact part 56 of the rotary member 44 and a first stationery plate part 40 of a stationery member 38, and an absorption amount of rotational energy of the spool 18 can be continuously increased in association with a rotation amount of the rotary member 44.SELECTED DRAWING: Figure 1
【課題】スプールの回転量の増加に伴うスプールの回転力の吸収量の増加を継続できるウェビング巻取装置を得る。【解決手段】本ウェビング巻取装置10では、車両緊急時に回転部材44がスプール18に連結され、回転部材44がスプール18と共に回転される。これによって、回転部材44の摺接部56と固定部材38の固定第1プレート部40との間で発生された摩擦力によってスプール18の回転力の一部を継続的に吸収でき、スプール18の回転のエネルギーの吸収量を、回転部材44の回転量の増加に伴い継続的に増加できる。【選択図】図1
