An air-conditioning apparatus comprising: a body;
a decorative panel defining a lower surface of the body; an air-inlet grille that is attached to an air inlet of the decorative panel and can rotate to open and close; and
a shaft disposed on the decorative panel, the shaft being movable along an axis of rotation of the air-inlet grille,
wherein the shaft includes a shaft body,
a pivot protruding from one end face of the shaft body in a moving direction of the shaft, and
a rib extending parallel to the pivot,
wherein the air-inlet grille has a mating hole into which the pivot is inserted to support rotation of the air-inlet grille,
wherein the pivot is fitted in the mating hole at a first limit of a movable range of the shaft, and
wherein the rib engages the decorative panel while the pivot is fitted in the mating hole. [Claim 2]
The air-conditioning apparatus of claim 1, wherein the rib has a tip located farther than base part of the pivot in the moving direction of the shaft. [Claim 3]
The air-conditioning apparatus of claim 1 or 2,
wherein the shaft body includes a shaft protrusion on a face of the shaft body that extends in the moving direction,
wherein the decorative panel includes a panel protrusion located on a path along which the shaft protrusion moves, and
wherein the panel protrusion is disposed between a position of the shaft

protrusion at the first limit of the movable range of the shaft and a position of the shaft protrusion at a second limit of the movable range of the shaft. [Claim 4]
The air-conditioning apparatus of any one of claims 1 to 3, wherein the air-inlet grille includes a movement limiter that limits movement of the shaft while the air-inlet grille is closed. [Claim 5]
The air-conditioning apparatus of claim 4,
wherein the movement limiter is located on a path for the shaft while the air-inlet grille is closed, and
wherein a distance between the movement limiter and the mating hole is shorter than a distance between an abutment face of the shaft body that comes in contact with the movement limiter when the shaft moves and a tip of the pivot. [Claim 6]
The air-conditioning apparatus of claim 4 or 5, wherein the shaft body has a slope sloping in such a manner that an amount of interference with the movement limiter increases toward the pivot.
