| Zusammenfassung: | A valve shaft support structure is closed to improve its durability, lower its manufacturing cost and improve its quality, in which a valve shaft interposed between runners is formed as an eccentric shaft integrally formed with a valve. A valve and a valve shaft are formed in a body to support the valve. An eccentric circular protrusion is formed in a center portion of the valve shaft, and divided manifold bodies support the eccentric circular protrusion. The valve shaft and the manifold bodies are repeatedly in contact or non-contact with each other when the valve is opened or closed. |
