Claims

[Scope of utility model registration request]

(1) In a valve operating system for an internal combustion engine in which a cylinder head is provided with an intake valve and an exhaust valve arranged to sandwich a plane including the axis of the cylinder, and a single camshaft that drives these valves, the camshaft is arranged so as to be offset to one of the intake/exhaust valves, and a first support shaft is arranged close to one of the valves, and a second support shaft is arranged close to the other valve. a support shaft, a cam follower swingably supported by the first support shaft and engaged with the camshaft, a rocker arm supported by the second support shaft and engaged with the other valve, the cam follower and A bushing rod is interposed between the rocker arms and transmits the valve opening force transmitted from the camshaft to the cam follower to the other valve via the rocker arm, and the bushing rod is biased so as to eliminate a clearance between the cam follower and the rocker arm. A valve operating system for an internal combustion engine, comprising: an elastic member provided between the cam follower and the rocker arm.

(2) In the utility model registration claim 1, the elastic member is a coil spring that is stretched across the cam follower and rocker arm and biases the bushing rod so that the cam follower and rocker arm sandwich the bushing rod. Valve train.

(3) In the utility model registration claim described in claim 1, the elastic member has one end locked on the end side of the bushing rod and the other end locked on the cam follower or rocker arm, and the end of the bushing rod and the cam follower or rocker arm are pressed together. A valve train for an internal combustion engine is an elastic plate-like member that urges the valve to move.
