PROBLEM TO BE SOLVED: To provide an electronic controller capable of appropriately positioning an anchoring protrusion of a cover to an adhesive in a seal groove.SOLUTION: Positioning pins 22 to 26 for inserting into each of positioning holes, are provided on a cover 3, while first to forth positioning holes 13 to 16 are perforated at four corners of a case 2 for housing a circuit board 1. An anchoring protrusion 21 pushed and fitted into an adhesive 11 of a seal groove 10, is projected on a lower surface 20a of a fitting piece of the cover 3, while a seal groove 10 to be filled with an adhesive 11, is formed over the whole peripheral wall 2b of the case. The first positioning hole 13 is formed so as to have a referential minimum diameter, the second positioning hole 14 is formed so as to be a long hole in lateral direction, the third and the forth positioning holes 15, 16 are formed so as to have a relative large inner diameter, thereby the pins can move in lateral direction and radial direction. |
