ABSTRACT:
A collision impact detector detects deceleration of a vehicle caused by its collision with another vehicle or an obstacle. A rotor is rotatably supported on a shaft and biased by a coil spring in a direction opposite to a rotational direction in which the rotor is rotated by the deceleration. One axial end of the coil spring is supported by a first support integrally formed with the rotor, and the other axial end of the coil spring is supported by a second support formed separately from the rotor. In this manner, a friction torque generated between the coil spring and the second support is eliminated, thereby considerably reducing a total friction torque associated with rotation of the rotor. The second support may be formed either integrally with or separately from a housing supporting the shaft.
