| 发明名称 | Seatbelt retractor and seatbelt apparatus including the same | ||
| 摘要 | 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. | ||

| 主权项 | 1. A seatbelt retractor comprising: at least a spool configured to retract a seatbelt; drive means for rotating the spool; and a rotation detecting member configured to detect the amount of rotation of the spool, the amount of rotation of the spool being controlled by driving and controlling the drive means on the basis of the amount of rotation of the spool detected by the rotation detecting member, wherein the rotation detecting member is disposed eccentrically with respect to a rotating shaft of the spool in a radial direction of the rotating shaft, and wherein the rotation detecting member is disposed in a direction in which the rotating shaft is separated from the rotation detecting member by a load applied from the seatbelt to the spool in an emergency. | ||
