PROBLEM TO BE SOLVED: To make a plurality of members constituting a square-type frame become common, thereby reducing kinds of metal molds as well as kinds of components, and in addition, suppressing occurrences of assembly errors.SOLUTION: A square-type frame 60 is constituted by an upstream member 70 to be disposed on the upstream side and a downstream member 80 to be disposed on the downstream side in a flow direction of air conditioning air. The upstream member 70 and the downstream member 80 are in a point-symmetrical shape to each other with a point positioning at the center of the upstream member 70 as the center of the symmetry when the upstream member 70 is viewed from the flow direction of air conditioning air.SELECTED DRAWING: Figure 3 |
