Claims

[Scope of claims for utility model registration] 1. At the end of the valve stem opposite to the valve face,
A valve cotter is provided with a large diameter portion projecting laterally in an arc shape over the entire circumference of the valve shaft, and an arcuate fitting groove formed on the inner surface along the outer peripheral surface of the large diameter portion. 1. A valve device for an internal combustion engine, characterized in that a groove is fitted into the large diameter portion and fitted onto the outer periphery of an end of a valve shaft with a clearance fit. 2. The valve device for an internal combustion engine according to claim 1, wherein the large diameter portion is integrally formed with an end of a valve shaft by protruding from the end. 3. The large diameter portion forms a fitting groove on the outer circumferential surface of the end of the valve shaft, and a separately formed engagement ring is tightly fitted into the fitting groove so that the outer side of the engagement ring protrudes. A valve device for an internal combustion engine as claimed in claim 1 of the registered utility model.
