Therefore, the surface of the conductive elastic body 35 exposed on the surface serves as an electrical connection surface. As shown in FIG. 1, the electric connecting member 22 does not have a non-conductive elastic body corresponding to the non-conductive elastic body 36 b on one side surface, but the other portions are substantially the same as the electric connecting member 20. Is the same as

In the board case 28, the board 14 is placed after the electrical connection member 20 is inserted into the through hole 32. The substrate 14 has two convex electrodes 37, 37 protruding from both surfaces (the upper surface and the lower surface in FIG. 1), and includes a light emitting diode (LED) 38, a surge killer 40, and the like. A transparent lamp cover 42 is attached to the substrate case 28 so as to cover the substrate 14, and whether or not the solenoid valve body 12 is energized can be visually recognized from the outside by turning on the light emitting diode 38.

7, 37, the electrical connection member 20, and the convex electrodes 24, 24 of the solenoid valve body 12 come into contact with each other with a predetermined pressure.

After inserting the electric connecting member 22 into the through hole 44, the connecting member 18 to which the conductor 16 is soldered is placed so as to come into contact with the electric connecting member 22.

A claw 52 is provided on the tip of the connecting member 18 at the upper end thereof.
The lid member 56 provided with the swing hook 54 having the
