<P>PROBLEM TO BE SOLVED: To materialize a motor fan advantageous in cost reduction by limiting necessary use quantity of expensive heat conduction support member. <P>SOLUTION: A depression part 2-13 depressing to correspond to an outer appearance shape of each heat generation element 5-3 or a depression part formed in a shape along each heat generating element outer appearance shape as one unit in an area where the heat generation element is arranged is formed on a stator retaining part inner surface facing to cover a control circuit, heat conductive support member is filled in a gap between the heat generating element and the depression part, preferably the gap 6 about 1 mm. Consequently, use quantity of the heat conductive member represented by expensive silicone rubber can be suppressed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
