As described above, in the vibration detecting unit and the pedometer of the present invention, the center of gravity of the first assembly substrate is always positioned directly below the rotation axis due to the action of gravity, and the vibration sensor also acts in the direction of gravity from the rotation axis. Since it is located across the surface of, the vibration in the vertical direction can always be detected as a main vibration component by a single vibration sensor without occupying a large rotation space. Therefore, even if the holding direction is changed, the vibration component in the vertical direction can be detected, and the device can be made inexpensive and small.

Further, since the rotary shaft of the first assembly substrate is arranged so as to form an angle with respect to the reference position, it is possible to detect the vibration in the front-back and left-right directions with respect to the reference direction of the housing. Therefore, the housing can be rotated and held every 90 degrees in any direction from the reference direction of the housing. Especially, if the angle formed by the rotation axis from the reference position is 45 degrees,
Since there is little difference in the magnitude of the vibration detection signal in the front-rear and left-right directions, the accuracy in the holding direction is stable.

Further, since the step counting means is provided on the second assembly substrate or the third assembly substrate and combined with other assembly substrates to be unitized in advance, production control becomes easy and the efficiency of assembly is improved. Therefore, it can be made inexpensive.

Since the second assembly board is provided with the third rotating portion, the second assembly board rotates in a direction perpendicular to the direction of the rotation axis of the first assembly board, so that all the directions can be changed. On the other hand, the vibration in the vertical direction can always be detected. Therefore, it can be used in a wide range such as being carried in a bag or a pocket.

Further, since the connecting parts of the rotating parts are in close contact with each other, the rotating parts do not shift in the directions of the rotating shafts. Therefore, when detecting the vibration, noise components other than the vibration component in the vertical direction are detected. Can be prevented and accurate measurement can be performed.

Further, since the vibration sensor is provided with the weight at the free end, the sensitivity of the vibration sensor is improved, the detection sensitivity is increased, and reliable measurement is possible.

Further, since each rotating part is composed of a pair, even if an impact is applied to the rotating part, it is dispersed, and even if the pedometer is dropped, it is hard to break.
