A seat belt take-up device provided with an emergency-locking mechanism and having means for detecting a speed change of a vehicle above a predetermined value and in which webbing take-up means is locked upon detection of the speed change comprises a rotatable member provided concentrically with the take-up means and rotatable with the take-up means when in normal condition, stopping means for stopping the rotation of the rotatable member in response to the detecting means when there is a speed change of the vehicle above a predetermined value, a support member provided in axially juxtaposed relationship with the rotatable member and integrally with the take-up means, pawl means including at least one pawl member provided on the support member and capable of assuming a lock position and a non-lock position, the pawl member being normally in the non-lock position, an engaging member provided on the rotatable member for moving the pawl member to the lock position when the rotatable member is moved relative to the take-up means, and lock means engageable when the pawl member is moved to the lock position to stop rotation of the take-up means, the detecting means having an inertia member for sensing a webbing draw-out acceleration. |
