To provide a valve device which can maintain the engagement relation between a rod mechanism and a valve mechanism even when the range of advance/retraction of the rod mechanism increases, as well as can achieve downsizing of the entire valve device. In a valve device 1, a pressing rod 215 has a first driving surface 217 which remains in contact with a tip portion 312 from a position away from a rotation axis Axb to at least a position closest to the rotation axis Axb, and a second driving surface 218 which, after the contact relation between the tip portion 312 and the first driving surface 217 is dissolved, remains in contact with the tip portion 312 to a position past the rotation axis Axb. |
