  As a result, after assembling the gear holder guide 41 between the pair of left and right guide rails 40 on the base 31, the assembling work is simplified and simplified as compared with the case where the drive motor 44 is installed on the back side thereof, and the man-hour is greatly increased. Can be reduced. The lower guide pin of the gear holder guide 41 may be inserted into the rail portion from the lower end portion of the guide rail 40 as described above, and the cutout portions 47 need not be provided at a plurality of locations.

  Furthermore, the rail cover 48 is detachable with screws or the like, and is configured to be able to restore the rail function of the guide rail 40 by being installed in the notch 47, and with the rail cover 48 removed. By opening the notch portion 47 and inserting the upper guide pin 42A on the gear holder guide 41 side into the rail portion of the pair of left and right guide rails 40, the output shaft 45 of the drive motor 44 protruding to the front side is obstructed. The gear holder guide 41 can be incorporated into the guide rail 40 without any change. On the other hand, after the gear holder guide 41 is assembled, the rail cover 48 is attached and installed to restore the rail function of the guide rail 40 to the original state. The guide 41 can be slidably guided along the guide rail 40. Therefore, the drive motor 44, the guide rail 40, and the gear holder guide 41 can be sequentially assembled by attaching and detaching the rail cover 48, and the lifting mechanism 21 can be easily disassembled and assembled even during maintenance.

  Further, the gear holder guide 41 is a vertically long rectangular frame, and the rack gear 43 is integrally provided along the length direction at a substantially central portion in the frame. The gear holder guide 41 itself can be reduced in weight by making the gear holder guide 41 to hold | maintain into a frame structure, and reducing the usage-amount of a constituent material. Accordingly, the material cost can be reduced and the cost can be reduced, and the drive motor 44 that raises and lowers the gear holder guide 41 can be reduced in size and the power consumption can be reduced.

  Further, the gear holder guide 41 is configured such that a plurality of reinforcing horizontal lattices 41 </ b> A are integrally formed between one vertical frame and the rack gear 43. For this reason, even if the gear holder guide 41 has a frame structure, the flexural strength can be sufficiently ensured by reinforcing the rack gear 43 that is long in the vertical direction with a plurality of horizontal lattices 41A. Accordingly, the meshing between the rack gear 43 and the gear 46 can be maintained normally, and the gear holder guide 41 can be smoothly moved up and down along the guide rail 40 by the rotation of the drive motor 44.

  Furthermore, in this embodiment, the shutter 20 and the lifting mechanism 21 are connected via a connector 49 in which the lower end portion of the shutter 20 and the upper end portion of the gear holder guide 41 of the lifting mechanism 21 are coupled to each other so as to be rotatable. The configuration is as follows. For this reason, by raising and lowering the gear holder guide 41 of the elevating mechanism 21 in the vertical direction, the shutter 20 connected to the upper end portion thereof via the connector 49 is given a degree of freedom in movement, and the air outlet 9 It is possible to move forward along the front side while moving up and down along. Therefore, the shutter 20 that opens and closes the air outlet 9 can be easily moved to the position when the air outlet 9 is closed and the accommodation position when the air outlet 9 is opened.

  In addition, this invention is not limited to the invention concerning the said embodiment, In the range which does not deviate from the summary, it can change suitably. For example, in the above-described embodiment, the upper guide pin 22 and the lower guide pin 23 are guide pins having the same configuration and shared, but an example in which the pin length is different may be used. Of course. The upper guide pin 22 and the lower guide pin 23 and the upper and lower guide pins 42A and 42B provided on the gear holder guide 41 of the elevating mechanism 21 may be configured in common.

  Furthermore, in the said embodiment, in the raising / lowering mechanism 21 which raises / lowers the shutter 20, although the gear holder guide 41 and the rack gear 43 are integrally molded products by resin, it does not necessarily need to be an integrally molded product, and it shape | molded separately. It is good also as a structure which combined things. Although the gear holder guide 41 is a frame, a part of the plate material may be punched into a rectangular shape, and a rack gear 43 may be provided on the end face of the punched portion.
