PROBLEM TO BE SOLVED: To obtain a webbing winder which can change the resistance of rotation to a drawer direction which is imparted to a spool according to a magnitude of rotation acceleration to the drawer direction of the spool.SOLUTION: When a webbing winder 10 is rotated to a drawer direction together with a spool 18, a rotation delay occurs at the other side of a friction belt 56 in a longitudinal direction with respect to one side of the friction belt 56 in the longitudinal direction, and the other side of the friction belt 56 in the longitudinal direction is wound to a friction force generation part 46 of a ring 40. By this constitution, a first friction force is generated between the other side of the friction belt 56 in the longitudinal direction and the friction force generation part 46 of the ring 40. Furthermore, as rotation acceleration to the drawer direction of the spool 18 becomes large, a winding range of the friction belt 56 to the friction force generation part 46 of the ring 40 becomes wide, and the first friction force becomes large.SELECTED DRAWING: Figure 1
【課題】スプールの引出方向への回転加速度の大きさに応じてスプールに付与される引出方向への回転の抵抗を変えることができるウェビング巻取装置を得る。【解決手段】ウェビング巻取装置10では、スプール18と共に引出方向へ回転されると、摩擦ベルト56の長手方向一側に対して摩擦ベルト56の長手方向他側で回転遅れが生じ、摩擦ベルト56の長手方向他側がリング40の摩擦力発生部46に巻付く。これによって、摩擦ベルト56の長手方向他側とリング40の摩擦力発生部46との間で第1の摩擦力が発生される。しかも、スプール18の引出方向への回転加速度が大きいほど、摩擦ベルト56のリング40の摩擦力発生部46への巻付き範囲が大きくなり、第1の摩擦力が大きくなる。【選択図】図1
