Abstract
An apparatus for detecting a collision of a vehicle of the like has a main body which includes a rotational member comprising an eccentric weight member and two cam members, a spiral spring member which is deformed and applies a counteracting rotational force to the rotational member in response to the occurrence of impactive acceleration or deceleration of a vehicle or the like when the magnitude of the acceleration or deceleration exceeds a predetermined value, contact which is actuated by the two cam members to be opened or closed when the rotational member rotates against the countertorque by the spiral spring member to reach a predetermined angle of rotation, a base assembly, and a lid member. The collision detecting apparatus is completed by enclosing the abovementioned main body in a case with a retaining spring member intervening therebetween.
