PROBLEM TO BE SOLVED: To cut a vibration transmitting route while forming the electrical wiring of a vibration detecting means into the wireless structure by fitting a vibration detecting head and a transmitter means to a vibration resistant base, and fitting a receiver means to a part except for the vibration resistant base. SOLUTION: A vibration detecting head 8, a transmitter 9 and a regulator 17 are provided on a vibration resistant base. On the other hand, a receiver 12 and a power source oscillator 14 are fitted to members except for the vibration resistant base, for example, an electrical lack. Namely, the signal for showing the vibration of the vibration resistant base picked up by the vibration detecting head 8 is transmitted on the wireless to a place except for the vibration resistant base. Acceleration signal of each part of the vibration resistant base obtained from the receiver 12 is appropriately filtered when necessary so as to eliminate the high frequency noise, and quickly input to a computing means for extracting the movement mode related to the acceleration. |
