<p>The outlet flow path (5) of a wall-hung indoor unit (1) has, in a cross-sectional view thereof, an upstream section (51) and a downstream section (52) which has an expanding flow path width. The downstream section (52) has a guide wall (53) which is curved to a large extent and a facing wall (54) which faces the guide wall (53) and is curved to a small extent. The wall-hung indoor unit (1) is provided with a protrusion member (6) which can be caused to protrude to the inside of the outlet flow path (5) from the facing wall (54) side. The switching between a first blowing state in which conditioned air is caused to flow in the direction along the guide wall (53) and a second blowing state in which the conditioned air is caused to flow in the direction along the facing wall (54) is performed by switching the protrusion member (6) between a protruding state and a non-protruding state. The guide wall (53) is convex to the outlet flow path (5) side.</p>
