ABSTRACT:
A webbing retractor includes a take-up shaft, an inertia plate provided integrally and coaxially with the take-up shaft, and an inertial force imparting mechanism. When a webbing for restraining a vehicle occupant is suddenly pulled-out, the take-up shaft takes-up the webbing, and the inertia plate causes a rotational delay with respect to the take-up shaft, and rotation of the take-up shaft in a webbing pull-out direction is thereby locked. Further, the inertial force imparting mechanism that suppresses and deters rotation of the inertia plate in a webbing take-up rotation direction by the inertial force imparting mechanism applying inertial force in a webbing pull-out rotation direction to the inertia plate which attempts to rotate in a webbing take-up direction even after rotation of the take-up shaft in the webbing take-up rotation direction has stopped when a vehicle occupant cancels an applied state of the webbing and the entire webbing is taken-up.
