VIBRATION ISOLATING DEVICE PROVIDED WITH ELECTROMAGNETIC EXCITING MEANS

摘要

PROBLEM TO BE SOLVED: To reduce or prevent a decrease in generation efficiency and control accuracy of excitation force in the case of adopting a metal-made bobbin, in a vibration isolating device provided with an electromagnetic exciting means. ;SOLUTION: Relating to a metal-made bobbin 34, a slit 44 extended in a direction almost orthogonal to the winding direction of a coil 22 is formed. That is, based on that the primary cause of problem generated in the case of adopting the metal-made bobbin 34 is newly found out in an eddy current, this invention is completed, and by reducing the eddy current in the bobbin 34 by the slit 44, problems of decrease of generation efficiency, decrease of control accuracy., etc., of exciting force caused by the eddy current can be all favorably solved.;COPYRIGHT: (C)1998,JPO
