Abstract
In a valve device, a housing has a mounting portion that contacts a back surface of a stationary disk which is opposite to a contact surface of the stationary disk while the contact surface is opposed to a rotor. One of the stationary disk and the mounting portion has a receiving groove that receives a gasket which seals a gap between the stationary disk and the mounting portion. The gasket has: two seal surfaces that are opposed to the stationary disk and the mounting portion, respectively; and at least one lateral projection that is opposed to a groove lateral surface of the receiving groove and projects toward the groove lateral surface. The gasket is press-fitted into the receiving groove in a state where the at least one lateral projection is in contact with the groove lateral surface.
