Abstract
A valve system for an internal combustion engine has first rocker arms supported by a rocker shaft such that they rock when driven by first cams; a second rocker arm supported by the rocker shaft such that it rocks when driven by a second cam, the second rocker arm being disposed adjacent to the first rocker arms; a connection switching mechanism that switches the first rocker arms between a state of being connected to the second rocker arm and a state of being disconnected from the second rocker arm; a forcing member that forces the second rocker arm toward the second cam while the second rocker arm is rocking; a supporting member rotatably supported by a support shaft provided on a cylinder head to support the forcing member; and a locking structure that inhibits the supporting member from rotating about the support shaft.
