Abstract
In a webbing retractor, the center of a rack and rack-teeth in an axial direction of a pinion is placed on the opposite side of a leg plate side with respect to the central axis of a cylinder. The piston is acted upon by a tilting-force toward the leg plate side from the pinion. A stop portion of an upper stay is placed on another leg plate side of the leg plate. Even when the piston is acted upon by the tilting force toward the leg plate side from the pinion, the stop portion can stop the movement of the leg plate toward the other leg plate side, and tilting of the piston and the cylinder toward the leg plate side can be suppressed. Moreover, the need to increase the strength of a frame and so forth can be eliminated, so the webbing retractor can be made compact and lightweight.
