PROBLEM TO BE SOLVED: To realize reduction in raw material cost of a plate spring material of high unit price, while maintaining reliability. SOLUTION: In this collision detecting device 200, a long weight body 1 from side to is adopted, and a pair of contact members are composed by a movable member 4 and a fixed member 50. The weight body 1 and a rotor 3 are rotated in an a-direction around a rotary shaft 2 when it receives deceleration exceeding a prescribed quantity, and as a result the movable member 4 is pressed down by a cam 31 of the rotor 3. At that time, the collision detecting device 200 is operated by contacting of a contact 41 positioned near the head of the movable member 4 with an inclined contact face 51 of the fixed member 50. A normal line direction D of the contact face 51 is shifted from a displacement direction C of the contact 41 of the movable member 4 by about 30 degrees. These constitutions, since the drag received from the fixed member 50 is relaxed, the contact 41 no longer is repulsed by the fixed member 50, and a contact time between the contact members can be secured fully. Therefore, the device 200 functions effectively, similarly to a conventional collision detecting device.
