摘要:
A variable valve device includes a camshaft which is rotatably provided in an internal combustion engine while having a cam, a rocker shaft which is arranged next to the camshaft, a valve which is driven by the cam, a cam follower rocker which is rotatably provided in the rocker shaft, and is rocked by following the cam, a valve drive rocker which is rotatably provided in the rocker shaft next to the cam follower rocker, and drives the valve, and a switching portion which be able to switch the valve drive rocker between a drive state and a non-drive state. Either a body of the cam follower rocker or a body of the valve drive rocker is made of an iron-based metal material, and the other body is made of a material different from the iron-based metal material, heat treatment being not required in the different material.
