囲第１項記載のバルブ構造。[Claims for Utility Model Registration] (1) A ring member that has a stopper portion that restrains the spring retainer from protruding upward from the top dead center position and that guides the sliding surface on the outer periphery of the spring retainer is attached to the spring retainer. The spring retainer is fitted into the recess of the cylinder head in which the valve stem head is inserted, and the engagement protrusion provided on the valve stem head is inserted into the engagement opening provided on the spring retainer, and the valve is closed by rotating the engagement protrusion through a predetermined angle. A valve structure in which a stem head and the spring retainer are engaged with each other, and a flat plate-like lid body that comes into contact with the cam is fixed to the upper surface of the engagement protrusion. (2) The valve structure according to claim 1, wherein the valve stem between the valve stem head and the valve head is provided with a coil portion for absorbing thermal expansion of the valve stem.
