Abstract
A webbing take-up device includes a second clutch that transmits rotation of a motor to a spool. The second clutch includes a base including a first spring catch portion, a clutch gear, a clutch spring including a coil portion, having an end portion at one side caught to the first spring catch portion, and a lever that includes a second spring catch portion catching an end portion at another side of the clutch spring, and that enlarges diameter of the coil portion to abut the clutch gear by moving the end portion at the another side of the clutch spring toward one side in the circumferential direction of the base. A terminal end of the end portion at the one side of the clutch spring abuts the first spring catch portion when the lever is rotated toward the one side in the circumferential direction of the base.
