PROBLEM TO BE SOLVED: To reduce noise during operation of a vehicle sensor without occurence of rising of a price of a seat belt retractor.SOLUTION: A vehicle sensor 1 is mounted in a sensor storage chamber 4 of a case 3. A lever stopper 42 is formed integrally with the case 3. The lever stopper 42 abuts against a claw 8 of a sensor lever 7 thereby blocking rotation of the sensor lever 7, when a sensor weight 11 of the vehicle sensor 1 pushes up the sensor lever 7, whereby it is prevented that the claw 8 of the sensor lever 7 too enters between teeth 6, 6 of a gear 5. The lever stopper 42 is integrally provided with: an elastic deformation piece 48 which contacts the claw 8 of the sensor lever 7, and elastically deforms and absorbs an impact generated at the time of collision against the claw 8 of the sensor lever 7; and a load receiving surface (concave surface) which irregularly engages with a convex surface of the elastic deformation piece 48 elastically deformed by the claw 8 of the sensor lever 7 to prevent the deformation of the elastic deformation piece 48. |
