A bearing 19 provided at the center of the guide plate 14 is a support part provided vertically and integrally with the guide plate 14 to support the bearing 18. To explain this support part 19 in more detail, the bearing 18 has an outer ring 20 and holes 2 provided in the side plates 21 and 22 of the unit fans 10a and 10b.
3 and a ball 25 interposed between the inner and outer rings 20 and 24,
A part of the outer ring 20 is supported by a support portion 19. 26 is a hollow portion provided in the inner ring 24, and this hollow portion 26 is provided to make the bearing 18 lighter. Also, the distance A between the side plate 21 of the unit fan 10a and the side plate 22 of the unit fan 10b is
It is made slightly larger than the width of , and is configured with an interval A of about 2 mm. FIG. 4 is a sectional view of the wall-mounted indoor unit, which has a main body 27 with an inlet 8 and an outlet 29. A heat exchanger 30 has a drain pan 32 that also serves as a tongue portion 31 of the cross flow fan 11 below the heat exchanger. A support portion 19 that supports the bearing 18 at the center of the cross flow fan 11 is provided at the center of the front of the guide plate 14 so as to support a portion of the outer ring 24 of the bearing 18.

のである。Effects of the Invention As described above, when a longitudinally long crossflow fan has to be constructed, the present invention provides a bearing fitted to the side plate of the fan and a bearing supported in the longitudinal center of the crossflow fan. Since the space between the support part and each side plate is at least slightly larger than the width of the bearing, there is no vibration caused by deflection when the crossflow fan rotates, and the narrow spacing between each unit fan reduces its own weight. This eliminates deflection caused by the crossflow fan, improves its performance as a crossflow fan, improves durability, and contributes to compactness. Furthermore, the hollow portion provided in the center of the inner ring has the effect of reducing weight and reducing the burden on the supporting portion.
