PURPOSE:To reinforce the holding force to fix a substrate to a base member by providing a copper foil pattern at a specific position on the opposite side of a part-inserting surface of the substrate. CONSTITUTION:While the valve of a neowedge valve is inserted into a hole 6 from a part-inserting surface A of the lower side of a substrate 5, fixing pins are inserted in notches 7 and rotated so as to fix the valve. In this case, other than the substrate 5 and conductive patterns 8 at the part-inserting surface A, a holding force of the copper foil surfaces of copper foil patterns 9 provided to position at the lower side of the fixing pins is also added. Consequently, when the copper foil patterns 9 are installed by rotating them to a base member, a good installing force can be obtained, and a removal of the neowedge valve can be prevented easily in a simple constitution. |
