PROBLEM TO BE SOLVED: To provide an air conditioning device which is not unpreparedly moved and can be easily moved to another place.SOLUTION: An air conditioning device includes: a handle 9 attached to the upper side of a casing 1 to be able to advance; and a linking part that links the handle 9 to a braking part for a wheel 20 in such a manner that rotation of the wheel 20 is braked when the handle 9 is retracted inside the casing and that braking of the wheel 20 is canceled when the handle 9 is advanced from the casing. The braking part is composed of a pinion gear 20c provided to the wheel 20 and a rack gear 22 that can be engaged with the pinion gear 20c. The linking part includes a shaft 10 with one end connected to the handle 9, and an energizing means to energize the rack gear 22 toward an engagement canceling side. When the handle 9 is retracted, the shaft 10 presses the rack gear 22 to be engaged with the pinion gear 20c; and when the handle 9 is advanced, the shaft 10 moves away from the rack gear 22 to cancel the engagement with the pinion gear 20c. |
