摘要： A valve device which is lightweight and manufactured at low cost, limits to the minimum an influence of strain or distortion of a valve body caused from connection of external piping and the supporting of the valve to the outdoor unit frame or the like, and lowers reduces leakage of refrigerant as much as possible. The valve body 3 is provided at its one side in the axial direction of the cylindrical shape with an operation tool receiving part, at the side of a valve lid 6, for receiving the operation tool which turns a valve spindle, the valve body further provided at the other side in the axial direction with a connection tool mounting part for mounting a connection tool 8 by which an external piping is attached and detached, and, the valve body 3 moreover provided at the middle in the axial direction with a non-round trunk part 33 having a non-round cross section and a recessed part 34 concaved from the outside surface of the trunk part 33. A support member 4 consists of a trunk part engaging section 43, which engages with the non-round trunk part 33 to restrict or prevent the valve body 3 from turning and shifting in position, and a recessed part engaging section 44 which engages with the recessed part 34 to restrict or prevent the valve body 3 from axially shifting in position.
