鉛直に設けられる。 In the figure, 9 is a casing forming the upper wall and left and right side walls of the air conditioner, and 10 is a front grill, on which an inlet 11, an outlet 12, and a control section 13 are provided. 14 is an indoor heat exchanger, 15 is an outdoor heat exchanger, 16 is a partition plate that partitions the indoor side and outdoor side in the air conditioner main body, 17 is a cross flow fan on the outdoor side, and 18 is a cross on the indoor side. I'm a flow fan. Both of these cross flow fans 17,
18 are both provided vertically within the air conditioner main body, and their lower ends are connected to the rotating shaft of an electric motor (not shown) provided at the bottom of the air conditioner main body. Air flows in the direction of arrow 19, and air outside the room flows in the direction of arrow 2.
Flows in the direction of 0. Reference numeral 21 has a convex drawing part 22 which is fixed with screws or the like on a partition plate 16 that partitions indoor and outdoor areas with a top plate and which receives a bearing, and is centered on the central axes of the cross flow fans 17 and 18. It has a hole 23. This top plate 21 is the casing 9
It is arranged with a slight distance between it and the inner surface of the upper wall. A bearing bushing 24 is made of an elastic material such as rubber, and has a horizontal groove 25 formed on its outer periphery to fit into the hole 23. Furthermore, a ring-shaped dustproof part 26 is integrally formed on the upper part of the bearing bushing, and there is almost no gap between the upper end 27 of this dustproof part 26 and the inner surface of the upper wall of the casing 9, or they are in contact with each other. Reference numeral 28 denotes a bearing made of resin molding or metal, and supports a shaft 29 provided at the upper end of the cross flow fan 17. The bearing 26 is the bearing bushing 2
It is supported so that it is surrounded by 4. The bearing bushing 24 is vertically provided with a through hole 30 for the escape hole of the shaft 29.

属軸受体に比較してコストを安価にできる。 As is clear from the above structure, the bearing 26 is held by the bearing bushing 24 made of an elastic material such as rubber, and since this bearing bushing 24 is attached to the top plate 22, the cross flow fan 17 is unbalanced. Even if there is a vibration, the vibration is absorbed by the bearing bushing 24. Further, the bearing bushing 24 is an integrally molded product made of rubber or the like, and a vertical through hole 30 is provided for escape and die-cutting of the shaft 29.
By making the gap between the bearing 6 and the inner surface of the upper wall of the casing 9 extremely small, or by making them in contact with each other, the intrusion of dirt into the bearing 26 is prevented. Further, the bearing bushing 24 has the groove 2
5 can be fixed by fitting them into the holes in the top plate 22, and there is no need for screws, making assembly work easier. Furthermore, since the bearing bushing 24 is made of rubber or the like, the cost can be reduced compared to a metal bearing body.

A bearing is provided in the upper part of the air conditioner main body, and the bearing is connected to the rotating shaft of the electric motor fixed at the lower part and supports the shaft provided at the upper end of the cross flow fan, and the bearing is connected to a bearing bushing made of an elastic material such as rubber. The bearing bushing has a horizontal groove on its outer periphery, a ring-shaped dustproof part on the top, and a through hole that communicates with the bearing in the vertical direction. , since the bearing bushing is fixed to the top plate of the air conditioner using the groove so that the upper end of the dustproof part is close to or in contact with the inner surface of the upper wall of the casing of the air conditioner, the metal bearing body Compared to other products, it is cheaper to assemble and can be assembled simply by fitting the groove of the bearing bushing into the hole in the top plate instead of fixing with screws, etc., and since the bearing bushing is made of an elastic material, it has an excellent vibration-proofing effect. The ring-shaped dust-proof part can prevent dirt from entering the bearing, and the bearing has various advantages such as being prevented from coming off easily.
