PROBLEM TO BE SOLVED: To provide a webbing winding device capable of suppressing the lowering of friction force between a rotation transmission member and a rotator, even if the rotator is worn by friction between the rotation transmission member and the webbing winding device.SOLUTION: In a webbing winding device 10, a press-contacting portion 152 is protrusively formed from an inner peripheral portion of a body 101 of a clutch gear 100 toward the inside in a rotation radius direction of the body 101. When a diameter of a clutch spring 104 expands, the clutch spring 104 press-contacts with a tip end of the press-contacting portion 152. Circumferential dimensions of the press-contacting portion 152 gradually becomes short toward the tip end side thereof, and if the tip end is worn, a press-contacting range with the clutch spring 104 expands. |
