VIBRATION-PROOFING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a vibration-proofing device capable of stably obtaining greater output. SOLUTION: A length dimension of a magnetic pole section 125 is arranged to be a value in which a length dimension along a reciprocating direction of a shaft member 122 is greater than a length dimension along a direction orthogonal to the reciprocating direction of the shaft member 122. Therefore, output of an exciting means 200 can be improved by increasing the number of winding for a coil 126 while a width dimension (namely, a dimension in a direction orthogonal to the reciprocating direction of the shaft member 122) of the exciting means 200 is maintained at a small value. Additional frictional resistance can be avoided by supporting the shaft member 122 against the magnetic pole section 125 in a noncontact state so that the shaft member 122 and magnetic pole section 125 (a york section 124) are connected with a leaf spring 152. Therefore, reciprocation motions of the shaft member 122 can be stably carried out. COPYRIGHT: (C)2007,JPO&INPIT
