VIBRATION DETECTION STRUCTURE

Japanese Patent JP3881670

B2

PROBLEM TO BE SOLVED: To provide a thin vibration detection structure capable of using for a sensor measuring steps by detecting up and down vibration and a switch changing ON and OFF.
SOLUTION: The structure comprises a support pin having conductivity which is arranged in the center and connected with one polarity, an annular contact member formed in a ring shape with a large diameter concentric to the support pin in the center, a first swing member supported by the support pin to be rotatable, a second swing member fixed to the first swing member at a deviated fixing point shifted from the support pin, a work pore which is punched in the second swing member and coupled outside the support pin and of which the inner periphery can contact the support pin when the second swing member slides from the fulcrum of the deviated fixing point, and a contact shoe formed on the second swing member and slidable to a position contacting the annular contact member from the fulcrum of the deviated fixing point and an apart position not contacting. Between the first swing member and the second swing member, an energizing means for energizing the contact shoe to the direction parting from the annular contact member is provided.
