、を有するウエビング巻取装置用ロツク機構。 A take-up shaft that winds up occupant restraint webbing, a lock ring that uses a biasing force to follow the rotation of the take-up shaft in the webbing pull-out direction, an acceleration sensor that operates when an acceleration of a predetermined value or more is applied, and this acceleration sensor. A pawl lever that is actuated to apply a rotational resistance force to the lock wheel and cause a rotation delay with respect to the winding shaft; and a pole lever that rotates together with the winding shaft and causes the lock wheel to rotate with a rotation delay with respect to the winding shaft. a lock plate that moves in the radial direction of the take-up shaft; an internal gear wheel that engages with the lock plate when the lock plate is activated to stop the rotation of the take-up shaft in the webbing pulling direction; and a lock plate that is attached to the lock plate and the internal gear wheel, respectively. A guide plate and a guide gear are provided, and these contact each other before the lock plate meshes with the internal gear wheel, and the tips of the teeth of the guide plate are guided by the guide gear to prevent the tips of the lock plate and the internal gear wheel from coming into contact with each other. A lock mechanism for a webbing retractor, comprising: a guide means;
