PROBLEM TO BE SOLVED: To simplify coating application work of an adhesive and to form an assembly form suitable for mass production by respectively constituting adhesive induction spaces on the associated members for holding and fixing a printed circuit board. SOLUTION: A U-shaped groove part 214a is formed at the top end of a printed circuit board holding member 214 and a longitudinally long groove 214b is formed at the surface on a base plate 206 side. The position corresponding to the groove part 214a of the printed circuit board 209 is bored with a groove hole 209a. The substrate holding member 214 and the printed circuit board 209 are superposed on each other and are positioned in this state to the rising part 206a of the base plate 206 and are fixed by a U-shaped retaining spring 216. The adhesive is injected through the injection port 216a disposed at the apex of the retaining spring 216 into the groove part 214a of the substrate holding member 214 and is allowed to run into the groove part 214a, by which the holding member 214 is fixed onto the rising part 206a of the base plate 206. The adhesive flows to the hole part 209a of the printed circuit board 209 as well and connects and fixes the printed circuit board 209 and the substrate retaining plate. As a result, the packing of the adhesive is necessitated just once and the assembly suitable for mass production is embodied. |
