Abstract
A variable valve mechanism for an engine includes: a rocker shaft; a first rocker arm rotatably supported by the rocker shaft, for transmitting displacement of a first cam to a valve; a second rocker arm rotatably supported by the rocker shaft, for transmitting a displacement of a second cam to the valve; and a switching mechanism for switching a transmitting state and a non-transmitting state. The first rocker arm has a pair of first arm portions and a recess portion in which an upper end of the valve is inserted at an end portion of each of the first arm portions. The second rocker arm has a second arm portion disposed between the first arm portions. The first rocker arm is restricted from movement in an axis direction of the rocker shaft when an inner sidewall of the recess portion is in contact with the upper end of the valve. The second rocker arm is restricted from movement in the axis direction when the second arm portion is in contact with the first rocker arm.
