The screw feed type position adjusting mechanism raises the air path forming portion to the temporary fixing position set on the upper side of the setting range, and temporarily fixes and supports the position at that position. The air path forming portion is lowered from the temporary fixing position toward an appropriate relative position with respect to a grill plate fixedly attached to the main body portion at an appropriate assembling position. It is configured to function as a positioning means for positioning and supporting the camera. More specifically, the screw shaft 51 is rotated to position the distal end side tubular portion 24 at the temporary fixing position on the upper side of the set range, and the grill plate 6 is assembled at an appropriate assembly position. so,
The position can be adjusted by rotating the screw shaft 51 to move the distal end cylindrical portion 24 to an appropriate relative position located on the lower side of the set range.

(D) As described above, as the blow-out side portion in the circulation ventilation passage, instead of the configuration in which the distal end tubular portion 24 and the proximal end tubular portion 23 are provided separately, for example,
A configuration may be employed in which a bellows-type telescopic mechanism is employed to be able to expand and contract along the approaching / separating direction.

(2) In the above embodiment, the movable louver 11 and the electric motor 25 for operating the direction of the movable louver 11 are integrally supported by the distal end side tubular portion 24 at the blow-out side portion of the circulating air passage 7. Although the configuration has been exemplified, the present invention is not limited to such a configuration. For example, the configuration may be such that the position can be changed and supported on the main body side so as to correspond to the expansion and contraction direction of the blow-out side portion in the circulation ventilation path. . Further, instead of the configuration in which the electric motor is provided integrally with the movable louver, the configuration may be such that they are supported by separate members. For example, the movable louver may be arranged so that the vertical position can be changed freely and the electric motor is fixed. In this case, as a driving force transmission structure, a flexible tube capable of transmitting rotational power having flexibility can be used. Alternatively, the movable louver is not limited to a movable louver that can be freely changed in direction by an electric motor, and may be one that can be manually changed in direction.

(3) In the above embodiment, the external heat source K
Is provided with a heat exchanger 9 for heating the air passing through the circulation ventilation passage when hot water is supplied as a heat medium from the circulating air passage. In addition to the heat exchanger 9, heating is performed by supplying electric power. An electric heater may be provided in parallel, or the air passing through the circulation ventilation path may be heated only by the electric heater.

(4) In the above embodiment, in addition to the heating operation, each of the drying operation, the ventilation operation, and the cool air operation is provided, but the heating operation is provided. Only the heating operation and the drying operation may be provided, and the respective operation functions of the heating operation, the drying operation, and the ventilation operation may be provided.
