PURPOSE:To simply and rapidly fix a miniature motor, on which thermally decomposable foaming agent is coated on the outer surface, in a vibration preventive state by disposing the motor on an opposite supporting projections on a mounting surface and then heating to foam the agent. CONSTITUTION:Foaming agent 4, e.g., ethylene vinyl acetate, acrylic acid ester which is thermally decomposed by the heat of the degree not affecting the thermal influence to a body case 1 and is foamed, is coated and dried on the outer surface of a miniature motor 3, which is disposed between supporting projections 5 and 5 projected to face each from the motor mounting surface 31 of the case 1. The agent 4 is then heated and foamed by hot air heating means or the like, the gap between the motor 3 and the projections 5, 5 is hermetically buried and solidified with the foamed material 6, thereby fixing the motor 3 to the case 1. |
