摘要： In the webbing winding device, the rotation of the output shaft of the motor is transmitted to the spool via the first gear train. In this state, when the rotation speed of the spool decreases and the rotation of the slider base of the first clutch decreases, the coupling pawl of the second clutch is pressed by the slider provided on the slider base to mesh with the ratchet gear, and the rotation of the output shaft of the motor is transmitted to the spool via the second gear train.

摘要： In a webbing take-up device, a cover member is disposed on the inner side of a second peripheral wall of a second housing member. Due thereto, an outer side surface of a third peripheral wall of the cover member and an inner side surface of the second peripheral wall of the second housing member oppose each other in a radial direction of urging, which is a radial direction of rotation of rotational urging force of a flat spiral spring, so displacement of the cover member outward in the radial direction of urging can be suppressed.
