Abstract:
A valve device (1) is provided with: a valve housing (10) that has a housing-side sealing part that is provided around an upstream-side flow path that communicates with an intake air passage, an accommodation space that communicates with an EGR passage, a valve chamber that communicates between the upstream-side flow path and the accommodation space, and an opening that communicates between the upstream-side flow path and the accommodation space; a valve member that has a valve-member-side sealing part that blocks the intake air passage and the EGR passage when abutting against the valve-housing-side sealing part; a restriction part (41) that is provided in the valve housing so as to be incapable of relative movement; and an abutting part (42) that can rotate in synchronization with relative rotation of the valve member with respect to the valve housing and that can restrict the relative rotation of the valve member with respect to the valve housing when abutting against the restriction part (41). The restriction part (41) is provided separately from the valve-housing-side sealing part, and the abutting part (42) is provided separately from the valve-member-side sealing part.
