The present invention relates to a gasket for preventing external leakage of the coolant flowing through the water temperature regulator housing and the cooling water inlet side, the water temperature regulator is installed, and more particularly, the prevention piece for blocking the flow of the cooling water on one side of the gasket. It further relates to a gasket formed with a cooling water flow prevention piece to allow a smooth adjustment of the amount of cooling water by the water temperature controller by preventing the flow of any cooling water in addition to the cooling water to further control the water temperature.

In general, the temperature controller (THERMOSTAT) of the vehicle cooling system automatically opens and closes according to the change in the coolant temperature between the engine and the radiator to maintain the proper temperature of the coolant.

The water temperature regulator 1 is supported using a seat 4 mounted on the seat support surface 3 of the housing 2 as shown in FIG. 1, and fastened while the fitting 5 is covered thereon. Is installed as a structure.

However, in such a water temperature controller installation structure, there is a problem that the coolant is leaked to the site where the seat of the water temperature controller is placed, for example, the part where the fastening surfaces of the housing and the fitting are in close contact.

That is, due to the formation of the seat support surface for supporting the temperature controller, it was difficult to secure a sufficient airtight section at this site, and it was difficult to expect a satisfactory airtight effect.

Thus, by further introducing a gasket 6 between the seating surface 3 of the housing 2 on which the seat 4 of the water temperature regulator 1 is placed and the fitting 5, the housing 2 and the fitting ( The airtightness between 5) is improved to prevent the leakage of cooling water.
