Title:
VIBRATION DETECTOR
Document Type and Number:
Japanese Patent JPH01262424
Kind Code:
A
Abstract:
PURPOSE:To enable efficient signal detection by setting the diameter of a nut equal to or larger than the diameter of a weight and clamping the entire plane of the weight with the nut. CONSTITUTION:The cylindrical part 1c of a bush 1 is threaded, the nut 19 is clamped thereto, and a component is assembled between bearing surfaces 1a and 1b. Then the nut 19 is formed to the same diameter as the outside diameter of the weight 8 and clamped to the entire plane of the weight 8. Thus, the nut 19 is assembled so that it is clamped to the entire plane of the weight 8, so inertial stress corresponding to the mass of the weight 8 is applied effectively to a piezoelectric element 5, which generates a detection signal efficiently. Namely, the large detection signal is obtained for the same vibration. Namely, the weight may be small for obtaining the detection signal of small level.
