<p><P>PROBLEM TO BE SOLVED: To prevent breaking or the like of a wiring board due to dropping impact or the like by suppressing flexural deformation of the wiring board by utilizing a fan holder of a blower fan. <P>SOLUTION: The wiring board 1 on which a transformer T is mounted in its intermediate part in the direction of its width is arranged horizontally on a chassis 2. The blower fan 3 mounted on the chassis 2 is arranged in a concave 11 in the shape of a depressed corner which is provided for the rear section of one side in the widthwise direction of the wiring board 1. The wiring board 1 is screwed in the chassis 2 at two points at its anterior end, and at two points at its posterior end. A piece 4 of plate which is integrally molded with the fan holder 31 is used as a substrate deformation suppressing member, by extending it over from a corner 11a in the shape of a depressed corner of the concave 11 of the wiring board 1. The flexural deformation of the wiring board 1 can be suppressed by bringing the wiring board 1 into contact with the piece 4 of plate. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
