ABSTRACT:
To inhibit an actuating member from being moved to a release position, to make the manipulation feeling satisfactory, and to provide a compact and cheap buckle device.
[Arrangement] When a large downward acceleration acts upon a buckle device 10, an upward inertia force F1 acts upon the gravitational center G of an inertia member 15 which is therefore rotated about a second support boss 17 so that a movement inhibiting part 15a abuts against the side wall of a second projected part 12b. in this condition, when a large upward deceleration acts upon the buckle device 10, large downward inertia forces F2, F3 act upon the gravitation center of an actuating member 12 and the gravitational center G of the inertia member, and accordingly, the actuating member 12 and the inertia member 15 are moved downward. When the upper end of a first hole 15c abuts against a first support boss 16, the inertia member 15 is inhibited from further moving downward, and when a step part 12c abuts against the upper end the movement inhibiting part 15a, the actuating member 12 is inhibited from further moving downward, by means of the inertia member, thereby the actuating member 12 will not move to the release position.
