A webbing retractor including: a take-up shaft that can take-up a webbing that is applied to a passenger, that takes-up the webbing by being rotated in a take-up direction, and that is rotated in a pull-out direction due to the webbing being pulled-out; a restricting member that, by being operated, restricts rotation of the take-up shaft in the pull-out direction; a driving portion that, by being electrically driven, changes an operating state of the restricting member; and a control section that acquires an acceleration of any of the webbing, the passenger or a vehicle, that computes jerk related to the acceleration, and that controls the driving portion such that the restricting member operates in a case in which the acceleration exceeds a first threshold value and the jerk exceeds a second threshold value.
