Abstract
Provided is a valve body that changes a communication state of a flow path through which liquid flows, the valve body comprising a valve main body formed of synthetic resin and comprising inside a press-fit fixing cylinder made of metal, and a drive shaft that is press-fitted in and fixed to the press-fit fixing cylinder of the valve main body. A non-press-fit portion comprising a space in a predetermined shape is formed in either one of the press-fit fixing cylinder and the drive shaft or both the press-fit fixing cylinder and the drive shaft. If the press-fit fixing cylinder is deformed to be expanded due to the press-fitting of the drive shaft, the deformation can be absorbed by the non-press-fit portion. This makes it possible to restrain a split or crack from being generated in the synthetic resin that forms the valve main body which is located around the press-fit fixing cylinder in which the drive shaft is press-fitted.
