A gear 12 having a support shaft 9 joined to the support shaft of the downward wind direction plate 8 is provided, and an intermediate gear 10 is provided between the two gears 11 and 12 to mesh with each other.
A motor 14 fixed to a mounting plate 15 is attached to a spindle 13 of the intermediate gear 10.
By connecting and driving the gear groups 10, 11, 12
The upper wind direction plate 6 and the lower wind direction plate 8 are rotated from the stop position where the air outlets are closed to the horizontal position and the vertical position via the. As a conventional technique related to the above-mentioned configuration, as in Japanese Patent Application No. 3-291450, the motor 14 for driving the vertical airflow direction vanes 6 and 8 and the driving force of the motor 14 are applied to the vertical airflow direction vanes 6 and 8. There is known an example in which a transmission mechanism (the gears 11 and 12 and the intermediate gear 10) is collectively arranged on one side of the vertical airflow direction vanes 6 and 8. Japanese Patent Application No. 3-29
In 1450, in the type in which the vertical wind direction plates 6 and 8 are operated by one motor 14, the number of assembling steps can be reduced by assembling the transmission mechanism (the gears 11 and 12 and the intermediate gear 10). Furthermore, the transmission mechanism (the gears 11 and 12 and the intermediate gear 10) is reduced to the motor 14
Since it is arranged directly on the side, the structure does not cause shaft twisting in transmission and does not cause synchronization delay. However, in the Japanese Patent Application No. 3-291450, the motor 14
And the transmission mechanism (the gears 11 and 12 and the intermediate gear 10)
By arranging and on one side of the vertical airflow direction vanes 6 and 8, the number of assembling steps is reduced, and further, there is an effect that a shaft twist is not generated in transmission and a synchronization delay is not caused. However, the motor 14 and the transmission mechanism (the gears 11 and 12)
And the intermediate gear 10) are joined to the vertical airflow direction vanes 6 and 8 before being assembled, and the motor 14 and the transmission mechanism (the gears 11 and 12 and the intermediate gear 10) are disengaged from each other. There was no disclosure of means for assembling so that there is no. Therefore, as described above, the motor 14 and the transmission mechanism (the gears 11 and 12 and the intermediate gear 10) are collectively disposed on one side of the vertical airflow direction vanes 6 and 8 and the mounting plate 15 is provided. The motor 14 and the transmission mechanism (the gears 11 and 12 and the intermediate gear 10) are assembled so as not to fall off from each other and assembled into an assembly.
It has been desired to reduce the number of assembling steps by joining the transmission mechanism (the gears 11 and 12 and the intermediate gear 10) to the vertical airflow direction vanes 6 and 8 to assemble them.
