造。[Claim for Utility Model Registration] A fan mounting plate is fixed to the upper or lower part of a unit mounting casing in which multiple board units are inserted and mounted by mounting electronic components on printed circuit boards, and cooling is carried out on this fan mounting plate. In the cooling structure of the unit mounting case in which a fan is provided for the unit mounting case, the fan mounting plate is provided with a movement hole extending in a direction perpendicular to the insertion direction of the board unit into the unit mounting case, and the area near both ends of the movement hole is provided. 2 to be located at
A book winding shaft is rotatably supported on a fan mounting plate, a sheet material is wrapped around both shafts, and the sheet material is stretched between both shafts so as to cover the moving hole, and The fan is attached to the sheet material, and the fan can be moved to a desired position within the moving hole by winding up the sheet material with one winding shaft and feeding out the sheet material from the other shaft. The mounting structure of the unit mounting case is characterized by:
