A webbing is smoothly wound and contained by the driving force of a motor, and high performance to restrict a passenger is obtained when the webbing is fastened. A webbing winding device (16) comprises a first transfer means and a second transfer means. The first transfer means transfers rotation of an output shaft to allow a winding shaft to be rotated in a winding direction as the output shaft is rotated in a first direction. When the second transfer means transfers rotation of the output shaft to allow the winding shaft to be rotated in the winding direction as the output shaft is rotated in a second direction, the second transfer means transfers the rotation within a range where a winding torque of the winding shaft does not reach a preset first torque. An electronic control unit (ECU) (172) rotates the output shaft (48A) of a driving means in the first direction to allow the winding torque to reach a preset second torque where restriction of a passenger is obtained when coupling of a tongue and a buckle is detected by a buckle switch (174), thereby allowing the webbing to be in close contact with the passenger.

    (과제) 모터의 구동력을 이용하여 원활한 웨빙의 권취 격납, 및 웨빙 장착시의 높은 탑승자 구속성을 얻는다. (해결 수단) 웨빙 권취 장치 (16) 는, 출력축이 제 1 방향으로 회전됨으로써, 출력축의 회전을, 권취축이 권취 방향으로 회전되도록 전달하는 제 1 전달 수단, 및 출력축이 제 2 방향으로 회전됨으로써, 출력축의 회전을, 권취축이 권취 방향으로 회전되도록 전달할 때, 권취축의 권취 토크가 미리 설정된 제 1 토크에 도달하지 않는 범위 내에서 전달하는 제 2 전달 수단을 구비한다. ECU (172) 는, 버클 스위치 (174) 에 의해 텅과 버클의 걸어맞춤이 검출되면, 권취축의 권취 토크가 미리 설정된 탑승자 구속성이 얻어지는 제 2 토크에 도달하도록, 구동 수단의 출력축 (48A) 을 제 1 방향으로 회전시켜, 웨빙을 탑승자에게 밀접시킨다.
