Abstract
The purpose of the present invention is to provide a motor vehicle internal combustion engine control apparatus which is constructed as a waterproof structure capable of having a long life while minimizing an increase in surface area of a case and a cover, thereby enabling miniaturization, decrease in cost, and increase in reliability to be satisfied. The motor vehicle internal combustion engine control apparatus is equipped with a substrate, a connector, and a case and cover which enclose the substrate, a waterproofing adhesive being disposed at a junction part between the cover and the case. Recessed portions are disposed at the junction part between the case and the cover. The sidewalls of one of the recessed portions are inserted into the other of the recessed portions to form a gap which is folded a plurality of times between the case and the cover and extends between the inside and the outside of the case and cover, said gap being formed so that the size of the gap on the outer side is formed to be larger than the size of the gap on the inner side. The gap is configured to be fluid-tight by the waterproofing adhesive filled in the gap.
