Webbing take-up device

A webbing take-up device, comprising:

• a spool to which a base end side in a length direction of a webbing is anchored, the spool taking up and storing the webbing by rotating in a take-up direction;
• a spring that biases the spool towards the take-up direction;
• a motor that rotates an output shaft about an axis thereof by being supplied with power;
• a first clutch that is provided between the spool and the output shaft, that transmits, to the spool, forward direction rotation of the output shaft, which rotation is reduced in speed by a specified speed reduction ratio, that rotates the spool in the take-up direction, and that does not transmit rotation arising on the spool side to the output shaft;
• and
• a second clutch that is provided between the spool and the output shaft independently of the first clutch, the second clutch comprising
• a clutch weight that is restricted from deploying at a time of forward direction rotation of the output shaft and that is permitted to deploy at a time of reverse direction rotation of the output shaft, and as a result of deployment of the clutch weight, the second clutch transmitting, to the spool, reverse direction rotation of the output shaft, which rotation is reduced in speed by a speed reduction ratio lower than the specified speed reduction ratio, and rotating the spool in the take-up direction, and the second clutch not transmitting rotation arising on the spool side to the output shaft,
• wherein the second clutch comprises a stopper that restricts the clutch weight from deploying at the time of forward direction rotation of the output shaft by abutting the clutch weight, but which permits the clutch weight to deploy at the time of reverse direction rotation of the output shaft.
