Abstract
A deceleration sensing member (7) includes a casing (7a), a lever (7b) having a pawl, and an inertia member (7c) that tilts to a two-dot chain position when deceleration exceeding a predetermined value acts on the vehicle. The bottom of the inertia member (7c) is formed in the shape of a small-mass portion (7j), while the top of the inertia member (7c) is formed in the shape of a large-mass portion (7k), so that the center of gravity of the inertia member (7c) lies at a relatively high position. Further, an actuating projection (7m) is formed on the large-mass portion (7k). Thus, it is possible to obtain a relatively large pivoting stroke of the actuator with a relatively small angle of inclination of the inertia member (7c). The deceleration sensing member (7) can be attached without play by longitudinally press-fitting engagement ridges (7g and 7h) into respective recesses (13j and 13k ). By virtue of the wedge effect produced by the slant side surfaces of the engagement ridges (7g and 7h) and the recesses (13j and 13k), each having a trapezoidal cross-sectional configuration, the casing 7a is attached to guide members even more rigidly.
