To provide a kinesimeter capable of more precisely measuring vibration and whole metabolizing amount when walking and when not walking despite of being a kinesimeter using a pendulum type detector of a uniaxial system.

The pendulum type detector 3 has a pendulum 36 capable of moving up and down, first and second movable contacts 50, 63 arranged in the lower and upper sides of the pendulum 36 respectively, and first and second immovable contacts formed corresponding to the movable contacts 50, 63 respectively, and is constituted of first and second boards 54, 63 arranged in the lower and upper sides of the pendulum 36 respectively, and biasing means 40 providing upwardly returning habit to the pendulum 36. The first movable contact 50 and the first immovable contact of the first board 54 constitute a first pendulum sensor 57 and the second movable contact 63 and the immovable contact of the second board 64 constitute a second pendulum sensor 68. The first movable contact 50 is spaced apart from the first immovable contact and the second movable contact 63 comes into contact with the second immovable contact when the pendulum 36 does not move.
