Claims

[Scope of utility model registration request]

In an internal combustion engine that has at least one of two intake valves and two exhaust valves for each cylinder, a swing arm that follows a cam of a camshaft to drive the same type of valve is equipped with a swing arm that has a single swinging fulcrum at one end and has a cam. A substantially T-shaped structure consisting of a follower member to be driven and a bridge member whose intermediate portion is rotatably supported by the other end of the follower member and whose both ends abut against the valve shaft ends of the same type of valve. A valve train for an internal combustion engine, further comprising a rotation restricting means for restricting a rotation range of the bridge member relative to the follower member to a minute angle.
