たことを特徴とするバルブ装置。 a valve body having a passage therein; a valve body that opens and closes the passage within the valve body; a shaft that transmits rotational force to the valve body; a seal between the shaft and the valve body; and a seal that connects the valve body to the valve body via the shaft. In a valve device comprising an actuator that applies rotational force, the shaft is composed of two, an actuator side shaft and a valve body side shaft,
In addition, a collar is formed in the center of the shaft on the valve body side, and a sleeve made of synthetic resin is placed on the inner diameter of the shaft hole in the valve body, so that the collar of the shaft on the valve body side comes into contact with the end surface of the sleeve. What is claimed is: 1. A valve device characterized in that a seat portion is provided, and the valve body is provided with a spring that presses a shaft on the valve body side toward an actuator side.
