Rotary type valve device

A rotary type valve device, comprising:

• a rotor having an internal passage formed around a predetermined axis and an opening portion which opens outward from the internal passage to an outer contour surface in a radial direction;
• a housing which supports the rotor to be rotatable with a predetermined first clearance and defines an axial passage communicating with the internal passage and a radial passage facing the outer contour surface and capable of communicating with the opening portion;
• a passage member disposed in the housing to define a part of the radial passage;
• and
• an annular seal member which seals a predetermined second clearance defined between an outer wall surface of the passage member and an inner wall surface of the housing,
• wherein the passage member comprises an annular contact portion which is pressed to be in close contact with the outer contour surface by a pressure of a fluid flowing from the axial passage, and a pressed portion pressed by the annular seal member to bring the annular contact portion into close contact with the outer contour surface by the pressure of the fluid flowing from the radial passage.
