Abstract
A transmitting gear is mounted on a rotating shaft of a spool so as to be rotatable integrally with the rotating shaft. A rotation sensor is disposed eccentrically with respect to the rotating shaft in a radial direction of the rotating shaft. The rotation sensor is disposed in a direction in which the rotating shaft is separated from the rotation sensor by a large load applied from a seatbelt to the spool in an emergency. The rotation sensor includes annularly arranged magnets and a magnet holding member that holds the magnets. The magnet holding member includes a receiving gear External teeth of the receiving gear engage with external teeth of the transmitting gear to increase a speed of rotation of the spool whose rotation is transmitted to the receiving gear.
