ハウジング１６はポート部２１に油密に装着される。Next, a method of mounting the solenoid valve 1'on the valve body 2 will be described with reference to FIG. Now, assuming that the inner diameter of the port portion 21 of the valve body 2 is D 1 , a flange-shaped projection 17 having a thickness W and an outer diameter D 2 larger than the above D 1 is formed on the outer surface of the resin valve housing 16 as the solenoid valve 1 ′. The resin valve housing 16 is press-fitted into the port portion 21 in the direction of arrow A to obtain the solenoid valve 1 shown in FIG. Before this press-fitting, the outer diameter D 2 of the collar-shaped protrusion 17 is the inner diameter D 1 of the port portion 21.
Because of the larger size, the press-fitting deforms the collar-shaped projection 17 to a greater or lesser extent, and the tip end of the collar-shaped projection 17 comes into close contact with the inner wall surface of the port portion 21 due to this deformation. 21 is oiltightly mounted.

油密状態に保持される。Further, the press-fitting causes a state in which an internal stress is generated in the collar-shaped protrusion 17, and the collar-shaped protrusion 17 constantly presses the inner wall surface of the port portion 21 due to this internal stress.
The resin valve housing 16 is mounted on the port portion 21 more reliably in an oiltight manner. The internal stress described above gradually decreases over time due to the stress relaxation phenomenon, and the pressing force also gradually decreases. However, the resin valve housing 16 and the port portion 21 are substantially long-term due to the following reasons. It is kept oiltight.

油漏れ量は実際上許容範囲内に留まる。That is, the solenoid valve 1 in operation is usually 100 to
Since it has reached a high temperature of about 160 ° C., it is pressed against each other at the contact interface between the valve body 2 made of metal and the valve housing 16 made of resin based on the difference in coefficient of thermal expansion between them, so that oil tightness is maintained. Since the oil that is secured and that is involved in the operation of the solenoid valve 1 is relatively highly viscous, even if there is some gap at the contact interface, the amount of oil leakage from it is actually within the allowable range. Stay in.

There is no particular limitation as long as the press-fitting is possible and the above-mentioned oil-tight state is achieved by the deformation of the collar-shaped projection 17 based on the press-fitting.
