Claims

[Scope of utility model registration request]

A cam that is attached to a camshaft and driven to rotate around the axis of the camshaft, a lid that is driven up and down by this cam, and a lid that supports the lid so that it can be raised and lowered freely. It has a lid guide that can reciprocate in parallel directions, a valve stem that engages with the lifter depending on the position of the lifter guide, and a valve that opens and closes the port by being driven by the cam via the lifter. , when the valve stem engages with the lifter, the valve is driven to open and close via the lifter, and when the valve stem is released from the lifter, the valve is stopped without being transmitted with the lifter's vertical movement. A valve train structure for an internal combustion engine characterized by the following.
