A lost motion spring is disposed to contact at one end an oscillating member interposed between a cam and a valve for synchronizing the oscillating of the valve with the rotation of the cam. The lost motion spring impels the oscillating member toward the cam. A spring support shaft is provided for supporting a second portion of the lost motion spring. A spring position adjustment mechanism is provided for adjusting the mounting position of the lost motion spring relative to the spring support shaft.
