摘要： A variable valve device of the invention has a structure in which, as connecting means for connecting a movable cam 22 located in an outer periphery of an outer camshaft 17a and an inner camshaft 17b located inside the outer camshaft 17a, there are provided a pin-like member 24 that is movably inserted so as to penetrate the movable cam 22, the outer camshaft 17a and the inner camshaft 17b along a diametrical direction of a shaft member 17 that is formed by turnably encasing the inner camshaft 17b in the outer camshaft 17a, and an escape-preventing portion 50 disposed in the end portion of the pin-like member 24. The movable cam 22 and the inner camshaft 17b are thus connected together while preventing large press-fit load and axial force from acting on components.
