<p>PURPOSE:To obtain an inexpensive sensor which has simple structure and no direction dependency by arranging a contact member around a spring element wire annularly. CONSTITUTION:A frame body 11 and the spring element wire 12, a weight 13, the contact member 14 and a contact moving means 15, etc., are provided. Then when the frame body 11 slants and the weight 13 rotates to a position 13' to abut on the member 14, a signal power source 16 turns on through a resistance 17, and consequently a specific detection signal S is outputted to an output means 18. Thus, when a car body slants, the element wire 12 flexes by the weight of the weight 13 without reference to the slanting direction and the weight abuts on the member 14. Consequently, a motion sensor showing the slanting is outputted. Further, even when a shock is applied to the card body, the sensor operates similarly. Therefore, even when the car body equipped with the frame body slants in any direction, that is detected immediately and the structure is simplified, so this sensor is easily obtained.</p> |
