Patent ID: 7758074

Claim:
A webbing retractor comprising: a rotating member by which, due to the rotating member being rotated in a take-up direction, a webbing is taken-up, and by which, due to the rotating member being rotated in a pull-out direction, the webbing is pulled-out; a pretensioner mechanism which, by being operated, rotates the rotating member in the take-up direction; and an engaging member which, due to operation of the pretensioner mechanism, is changed from a non-engageable state in which the engaging member cannot engage with the rotating member to an engageable state in which the engaging member does not engage with the rotating member and which engages with the rotating member only after operation of the pretensioner mechanism and after rotational force in the pull-out direction is applied, whereupon the engaging member immediately impedes rotation of the rotating member by engaging with the rotating member.
