Abstract
A variable valve mechanism includes a rocker arm including a first input arm, a second input arm, and an output arm, and a switch device that switches an operating state to a first state by coupling only the first input arm to the output arm, and switches the operating state to a second state by coupling only the second input arm to the output arm. The switch device includes two pins that are displaceably placed in the rocker arm and contact each other at their end faces, and a displacement device that switches the operating state to the first state by displacing a contact portion between the two pins to between the output arm and the second input arm, and switches the operating state to the second state by displacing the contact portion between the two pins to between the output arm and the first input arm.
