Abstract
An air conditioning apparatus has a case, a heat exchanger rotatable about a rotation axis in the case, and a pipe unit in communication with the heat exchanger. The pipe unit has a first section fixed to the case and a second section coaxially coupled to the first section. The second section is coupled to the heat exchanger and rotatable with the heat exchanger. The first section has a first annular portion, a second annular portion, a cylindrical portion, and a support member. The second section has a flange portion disposed between the first annular portion and the support member. An O-ring is disposed in a groove provided by the first annular portion and the cylindrical portion, and is in contact with a surface of the first annular portion and the flange portion in a direction parallel to the rotation axis.
