Abstract
A valve device is provided with a valve body driving member rotated by driving force from a drive source, and a valve body rotating in a circumferential direction integrally with the valve body driving member. Fitting parts fitted one another are formed in the lower surface of the valve body driving member and the upper surface of the valve body. The valve body has hole parts formed therethrough in the axial direction thereof. Groove parts that are flow channels linking from the outer peripheral surface of the valve body to the hole parts are formed in the upper surface of the valve body. The fitting parts and the groove parts on the valve body side have connecting parts that are portions where the fitting parts and the groove parts are formed continuously in the upper surface of the valve body without being separated by other elements constituting the valve body.
