A solenoid valve includes a non-magnetic main body having therein a solenoid coil and core, the core being formed of magnetic material and extending in the coil along the axial direction thereof. A plate member formed of a magnetic material is positioned at one end of the main body along the direction of movement of the core, and is integrally formed with the coil bobbin. A housing member having fluid communication passages therein is positioned adjacent the plate member at a side of the plate member opposite the main body. A valve structure actuatable by the core is positioned between the main body and the housing member for controlling fluid flow in fluid communication passages within the housing member. A yoke member formed of a magnetic material has a U-shaped including arms mechanically secured to the plate member, and has a bent portion mounted to the core.

Panties, briefs or like underwear includes a front piece 2 for covering lower abdomen, a rear piece 3 for covering buttocks and a connector piece 4 interconnecting the front piece 2 and the rear piece 3 for covering the crotch. The rear piece 3 is stitched at its lower end to the connector piece 4 while being stretched most greatly on the center line of the rear piece 3 and to a progressively lesser extent from the center line toward the opposite sides thereof. As a result, an elongated depression 6 extending vertically is formed on the center line of the rear piece 3 in conformity with the gluteal cleft between the buttocks. On the opposite sides of the depression 6, the rear piece 3 has rounded portions in conformity with the bulges of the buttocks.

The solenoid actuated valve device is comprised of a housing of magnetic material having a radially disposed inlet and at least one axially disposed outlet in communication with the interior of a hollow magnetic core disposed within the body. An annular bobbin having a solenoid coil wound thereon is slidably mounted on the core and is normally biased into a position closing at least one elongated radially extending opening through the core. Permanent magnets are secured to the interior of the body in such a manner that the lines of flux intersect the solenoid coil at right angles thereto. Two springs normally bias the bobbin to the closed position and extend between one end of the bobbin and a spring support member disposed adjacent one end of the body. Each spring is connected to one end of the coil and to a respective electrical terminal for supplying electric current to the solenoid coil and the position of the spring support is adjustable relative to the end of the housing by means of a screw threadably extending through the end of the housing into engagement with the spring holder to vary the spring force acting on the bobbin. The connection between the two springs and the ends of the solenoid coil are insulated from the bobbin to prevent a short circuit which would deprive the solenoid coil of electric current. The connections between the two springs and the terminals are also encapsulated with insulating material subsequent to the adjustment of the spring holder relative to the end of the housing.
