PURPOSE:To attenuate an electromagnetic oscillation and unbalanced oscillation, by supporting a motor with the elastic erection base of springs, supporting plates, and attenuation members combined with each other. CONSTITUTION:A motor 1 is supported by metallic plate springs 5, and the metallic springs 5 are supported by supporting plates 6. The rubbers 7 of attenua tion members are arranged between the supporting plates 6, supporting the metallic plate springs 5. By said composition, the coincidence of the frequency of magnetic oscillation with the inherent oscillation quantity of a frame system on the motor 1 supported by the metallic plate springs 5, the supporting plates 6, the rubbers 7, and a fitting base 8 is extremely relaxed because of the attenu ation effect of the rubbers 7, and so the magnitude of an oscillation mode is extremely reduced.
