Claims

[Scope of utility model registration request]

In an internal combustion engine having at least one of intake valves and exhaust valves, two for each cylinder, the position of a swing arm that follows a cam of a camshaft can be freely adjusted using a supporting member with an assist fulcrum formed at one end. , and is supported in a freely swinging manner, and a pair of arm portions extending from the swinging fulcrum portion toward the two valve shaft end portions of the same type are disposed in contact with the valve shaft end portions. Further, the swing arm is formed of a main body formed by bending a sheet metal so as to have an open portion on the upper surface, and a cam follower member attached to the main body and abutting the cam, and the support member of the main body and A valve operating device for an internal combustion engine, characterized in that portions that contact the end portions of the valve shaft are hardened, and a lubricating oil supply hole is formed to penetrate through the portions that contact the end portions of the valve shaft.
