<P>PROBLEM TO BE SOLVED: To prevent accumulation of a liquid such as water in a cover portion of a case opening, when an inverter storage case is mounted upside down on a vehicle or the like and the case opening is disposed below the case. <P>SOLUTION: A cover 30 for an inverter storage case is provided; and the cover 30 is in an approximately elliptic planar shape as a whole, in which a first screw hole forming portion 30a and a second screw hole forming portion 30b are formed on two parallel longitudinal sides at opposing positions in the transverse direction, with the screw hole forming portions 30a and 30b laterally arranged on the same side, and a side wall 30b is formed protruding perpendicular to a horizontal plane on the backside of the cover, on the perimeter of the whole shape. Through screw holes 30c are formed in the screw hole forming portions 30a, 30b, and a packing groove 30d is formed slightly inside and apart from the screw holes 30c, rounding the whole back face. A level difference face 30f is formed, which is a horizontal face and lower by a prescribed height h1 from the screw hole forming face 30e of the first screw hole forming portion 30a, and a through drainage hole 30g is formed in the level difference face 30f. <P>COPYRIGHT: (C)2012,JPO&INPIT |
