What is "baggage carousel"

n. A conveyor to transport luggage from aircraft, trains or luggage shuttles (outside) to claiming passengers (inside.)

A baggage carousel is a device, generally at an airport, that delivers checked luggage to the passengers at the baggage claim area at their final destination. Not all airports use these devices. Airports that do not have carousels generally deliver baggage by placing it on the floor or sliding it through an opening in a wall.
