Abstract
A variable valve mechanism has a switching mechanism for transmitting cam displacement to a first rocker arm from a second rocker arm. A camshaft is disposed obliquely above a rocker shaft. A first abutting portion and a second abutting portion are disposed in a dead space between an upper side of the rocker shaft and a side of the camshaft. The first abutting portion rotationally displaces in a rotational direction of rocker arms together with the first rocker arm. The second abutting portion rotationally displaces together with the second locker arm. The second abutting portion abuts on the first abutting portion from a rotating direction of rocker arms. In the switching mechanism thus configured, displacement of the second rocker arm is transmitted to the first rocker arm with reduced stress burden.
