Claims

[Scope of utility model registration request]

In a valve stem and rocker arm connection device in which the valve stem and rocker arm are brought into contact via a connector that is freely connected to an adjustment screw with an enlarged lower end spherical shape attached to the tip of the rocker arm, the upper end of the valve stem is formed into a quarter hemispherical surface. and a lower surface of the connector is formed into a concave spherical surface that fits into and slides into contact with the four hemispherical surfaces of the valve stem.
