Beschreibung
Zusammenfassung:	This ceiling-embedded air conditioner comprises: a motor having an output shaft rotatable about an axis; a turbo fan attached to the output shaft; and a heat exchanger that surrounds the turbo fan from the outer peripheral side and has a dimension in the axial direction which is larger than the dimension of the outlet flow path of the turbo fan in the axial direction. The turbo fan has: a main plate that is attached to the output shaft and has a disk shape about the axis; a shroud that is axially spaced apart from the main plate; an array of a plurality of circumferentially spaced-apart main blades provided across the shroud and the main plate; and a guide member having a guide surface that faces the shroud side while protruding circumferentially from a pressure surface, which is the surface of the main blade facing the forward side of the output shaft in the rotational direction.
