Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/188742
Kind Code:
A1
Abstract:
According to the present invention, a shutter for opening and closing a blow-out opening comprises: a pair of roller bases in which a first roller is disposed in an inward direction from each of two longitudinal-direction end parts; a base in which the roller bases are respectively provided to two width-direction side parts; a pair of first rails provided to each of the two side parts of the base, the first rails guiding the first roller; a pinion provided to the base, the pinion rotating due to driving by a motor; and a rack provided facing the base, the rack being meshed with the pinion. The base has a pair of second rails that guide a second roller. The rack has a pair of second rollers disposed widthwise at two longitudinal-direction end parts. The first roller presses the first rails in the inward direction of the shutter, and the second rollers press the second rails in the width direction of the shutter. This makes it possible to suppress unsteadiness produced toward the front, rear, left, and right when the shutter is operated or is stopped, and to preemptively prevent contact between the shutter and surrounding components due to the unsteadiness.
