PURPOSE:To accurately and objectively detect the vibration level in bodily sensation by providing a magnet to the free end of the leaf spring fixed to a rod-shaped rigid body while providing a coil forming a magnetic field crossing a magnet magnetizing direction at a right angle in the vicinity of the magnet. CONSTITUTION:A leaf spring 6 is fixed to a rod-shaped rigid body 2 and a magnet 8 is provided to the free end of the leaf spring 6 and a coil 12 forming a magnetic field crossing a magnet magnetizing direction at a right angle is provided in the vicinity of the magnet 8. The magnet 8 and the leaf spring 6 are set so as to be resonated at predetermined frequency on the basis of the wt. of the magnet and the spring constant of the leaf spring 6 and the coil 12 is excited by an electric signal having the above mentioned predetermined resonance frequency. As a result, the vibration level sensed by a human body, that is, the vibration level in bodily sensation can be detected accurately and objectively. |
