Claim 0:
1. A rotary-type valve device, comprising:
a tubular valve that comprises an inner passage and opening parts that are opened in an outer circumferential wall from the inner passage toward an outward side in a radial direction and that rotates about a predetermined axial line;
a shaft that rotates integrally with the tubular valve;
a housing that includes a housing main body and a coupling member coupled to housing main body, and is configured to accommodate the tubular valve and to, support the shaft such that the shaft is able to turn, and defines a communication port that is arranged in the coupling member and causes the inner passage to communicate with an outside, wherein the housing main body includes a partitioning wall that is opposite to the coupling member; and
a passage member that is assembled in the housing such that the passage member abuts on the outer circumferential wall of the tubular valve and is configured to define a passage in the radial direction,
wherein the tubular valve comprises a recessed part that is recessed inward from one end surface in a direction of the predetermined axial line and surrounds one end part of the shaft, and
the housing comprises a tube part that is configured to project inward from the partitioning wall in the direction of the predetermined axial line and is inserted into the recessed part and supports the one end part of the shaft and a support hole that is formed in the coupling member and next to the communication port and is configured to support an other end part of the shaft,
wherein the shaft has an annular end surface disposed on an inward side, in the direction of the predetermined axial line from the other end part, and
the coupling member comprises a thrust receiving part that is a part of the coupling member and projects towards the annular end surface from an other end surface of the tubular valve,
wherein the thrust receiving part is configured to support the annular end surface of the shaft, and
a diameter of the shaft in the tube part is larger than other parts of the shaft.
