Claims

[Scope of utility model registration request]

A gasket is attached to the lower edge of a cylinder head cover for an internal combustion engine, a grommet is attached to a through hole provided in the center of the cylinder head cover, and the grommet is pressed through an elastic member by a screw member screwed into the cylinder head, When installing a cylinder head cover for an internal combustion engine in which the lower end of the cylinder head cover is brought into close contact with the cylinder head via the gasket, the spring constant of the elastic member is set to be equal to or equal to the spring constant from the grommet to the lower end of the gasket. A device for installing a Rad force bar to a cylinder for internal combustion engines, which is characterized by being set smaller.
