PROBLEM TO BE SOLVED: To certainly make a sealant reside at an adhesive part while absorbing dimensional variation of a molding to secure adhesive performance.SOLUTION: An electronic control device has structure that a rail-like projection 5 of one case member engages into a groove-like recess 6 of the other case member, and is assembled by adhering both the case members by adhesives between the groove-like recess 6 of the case member and the rail-like projection 5 of the case member, in which the groove-like recess 6 of the case member has a first recess 6a having the narrow groove width on the bottom surface side and a second recess 6b having the wide groove width on the opening surface side, the first recess 6a is connected with the second recess 6b by a step part 6c with an inclination so that the groove width becomes wider from the bottom surface side toward the opening surface side, and the tip part of the rail-like projection 5 of the case member is constituted so as to engage into the first recess 6a on the bottom surface side of the case member. |
