Claims

[Scope of utility model registration request]

It has a cam, a lid that is driven up and down by the cam and can reciprocate in a direction substantially perpendicular to the direction of the up and down movement, and a valve stem that engages with the lifter. and a valve that is driven to open and close the port, the end of the valve stem extends beyond the lift amount of the valve, and the lifter has a protrusion extending beyond the lift amount of the valve, and the end of the valve stem extends beyond the lift amount of the valve. A space is formed in which the end of the valve stem can be accommodated, and when the end of the valve stem engages with the protrusion, the valve is driven to open and close via the lifter, and the end of the valve stem fits into the space. A valve train structure for an internal combustion engine, wherein when the valve is housed in the internal combustion engine, the valve stops without being transmitted with the lifting and lowering of the lifter.
