October 26, 2016
A webbing take-up device (10) includes a second clutch (116) that transmits rotation of a motor (66) to a spool (20). The second clutch (116) includes a base (118) including a first spring catch portion (125), a clutch gear (136), a clutch spring (140) including a coil portion, having an end portion at one side caught to the first spring catch portion (125), and a lever (148) that includes a second spring catch portion (146) catching an end portion at another side of the clutch spring (140), and that enlarges diameter of the coil portion to abut the clutch gear (136) by moving the end portion at the another side of the clutch spring (140) toward one side in the circumferential direction of the base (118). A terminal end of the end portion at the one side of the clutch spring (140) abuts the first spring catch portion (125) when the lever (148) is rotated toward the one side in the circumferential direction of the base (118).
