行う必要がある。2. Description of the Related Art A wind direction variable flap is provided at an air outlet of an indoor unit of a room air conditioner, and by moving the wind direction flap, cold air or warm air can be blown out in an appropriate direction into a room where air is conditioned. This wind direction variable flap has come to be able to automatically change the blowing direction from a manual operation using a stepping motor. This variable wind direction flap is located at the air outlet of the room air conditioner and is always in the air flow of the air blow so that it easily gets dirty and needs to be removed and cleaned.

て可動できるようになっている。As a drive structure for the variable wind direction flap, the rotary shaft of the variable wind direction flap is connected to the rotary shaft of the flap drive motor through a through hole provided in the side plate of the air outlet. It can be moved by a drive motor.

転シャフトには危険性がある。By the way, when removing the wind direction variable flap,
The shorter the rotating shaft is, the easier it is to remove. However, when the rotating shaft is shorter, the rotating shaft of the drive motor becomes longer, and the tip end is located near the through hole. At this time, when the facing distance between the live part of the drive motor and the rotary shaft cannot be made large, there is a risk of electric leakage to the rotary shaft, and there is a danger to the rotary shaft that is easily touched by a finger.

要がある。Therefore, it is necessary to use a large-sized and highly safe drive motor in which the live part of the motor and the coaxial shaft are separated from each other by a specified dimension or more. When such a drive motor is not used, the rotary shaft is Prevent the hands and fingers from getting into the vicinity of the rotary shaft by using a structure in which the rotary axis of the variable wind direction flap cannot be removed without the use of tools and jigs, and normally the variable wind direction flap cannot be removed. There is a need.

ある。In order to secure the insulation distance in the internal structure of the flap drive motor itself, the size of the motor becomes large, so that the indoor unit of the room air conditioner becomes large in size and it becomes difficult to manufacture a compact product. Also,
When using a motor whose insulation distance cannot be secured due to the internal structure, use a special tool to remove the wind direction variable flap.
It will be removed using a jig and handling is very inconvenient.

可能となってしまうものである。Further, if the interlocking position of the rotary shaft and the rotary shaft of the wind direction variable flap is formed in the inner part away from the through hole, the fingers inserted into the air outlet and the rotary shaft are separated from each other, which is safe. However, since the distance between the through hole and the tip of the rotary shaft becomes large, the variable wind direction flap is flexed to attach and detach, which makes it virtually impossible to attach and detach. .

By forming a fitting holding portion between the tip of the rotating shaft 6 of the variable wind direction flap 2 and the connecting body 7, the rotating shaft 6 rotates using the through hole 4 as a bearing, and The fitting and holding portion can be implemented with a simple structure that only transmits the rotational force of the connecting body 7. Further, even if the rotating shaft 6 guided by the tubular portion 4a is short, the rotational force is reliably transmitted. Therefore, when the variable wind direction flap 2 is removed, the tip of the rotating shaft 6 blows with a slight stroke. It came to move into the outlet 1, and the workability of attaching and detaching the variable wind direction flap 2 was improved.
