Description of the Related Art Conventionally, as shown in FIG. 1, an indoor unit of an air conditioner is detachable in a ventilation passage 6 connecting an inlet 1a at an upper portion of a housing 1 and an outlet 5 at a lower portion of the housing. The air filter 2, the heat exchanger 3, the cross flow fan 4 for sending the heat-exchanged conditioned air to the outlet 5, and the like are provided. As shown in FIG. 5, the cross flow fan 4 has a shaft 4a integrally mounted on one side of the cross flow fan 4 and a bearing provided on a first side plate 7a standing upright from a predetermined casing 7. The cross flow fan 4 is fixed to a shaft 8a of a motor 8 that rotates the cross flow fan 4 in a cylindrical bearing portion 4b having a screw hole 4b1 by being rotatably supported by a shaft 7a1 through a portion 7a1. And the connecting portion 10 is erected from the casing 7 to form an axial reinforcing rib 7b1.
Is surrounded by the second side plate 7b having Also,
The motor 8 is provided with a vibration isolating rubber 1 on a bearing 8 a of the motor 8.
1, the vibration-proof rubber 11 is inserted and accommodated in a vibration-proof rubber insertion portion 7c provided in the casing 7, and the casing 7 is locked to a base 1b behind the housing 1. I was trying to do it. However, in this configuration, when fixing the cross flow fan 4 to the shaft 8a of the motor 8 with the screw 9, it is necessary to visually search for a position where the cross flow fan 4 does not hit the casing 7 or the like. If fixed, the problem of generating abnormal noise will occur. Therefore, there is a long-awaited need for a structure that can reliably position the crossflow fan no matter who works.
