2. Description of the Related Art An air-conditioning case body having a frame-shaped housing on the inner front surface thereof is installed at an air-conditioning air outlet in a vehicle compartment, and the housing is vertically rotatable around a horizontal axis line in the air-conditioning case. There is a vehicle air conditioning blow-out device that changes the wind direction.

FIG. 6 shows an example of the air conditioning blow-out device,
According to the figure, the front surface of the air conditioning case body 1'forms a part of an arc when viewed from the side, and the front and rear louvers (not shown) that rotate left and right in the front space of the air conditioning case body 1 '. A frame-shaped housing 4'having a fixed horizontal louver 3'is rotatably supported around a horizontal axis. The vertical louver has upper and lower shafts rotatably supported by the upper and lower wall surfaces of the housing 4 ', and each vertical louver is rotatably connected by a single vertical louver interlocking link (not shown). By operating a knob (not shown) left and right to rotate one vertical louver left and right, all the vertical louvers simultaneously rotate left and right via the link. On the other hand, the horizontal louver 3'has a housing 4 '.
Is horizontally fixed to the front surface of the air conditioner, and the vertical wind direction is adjusted by rotating the housing 4'up and down around the left and right shafts inside the air conditioning case body 1 '.

When installing this type of air conditioning blow-out device for a vehicle, for example, on the ceiling of a vehicle, both ends of the case body of the air conditioning blow-out device to which various members are assembled are fastened to the ceiling panel with screws and then attached. A blind lid is attached to the screw head so as not to impair the external appearance. The work of attaching the blind lid is
Originally, this work has nothing to do with the installation of the air conditioning blower.

In order to eliminate such a problem, a screw hole is previously formed in the rear wall portion of the case body, and when the air conditioner blow-out device is attached to the vehicle panel through the screw hole, the screw hole is vertically moved inside the case body. The screw tightening by a driver from the outside is done through the gap of the louver surface formed on the front of the rotatably attached blow-out grill and the gap between the many wind direction adjusting plates mounted rotatably inside the grill. Done,
It is also attempted to eliminate the work of attaching the blind lid and prevent the appearance from being impaired.

[0006]

However, the same applies to the example of the air conditioning blowout apparatus shown in FIG. 6, but in the conventional vehicle air conditioning blowout apparatus having the air conditioning case body and the housing as described above, In general, the setting of the rotational position of the housing depends on the contact resistance between the protrusion protruding on the inner surface of the air conditioning case body and the outer surface of the housing, and the inclined posture of the housing is not stable in many cases. .

Further, according to the installation structure of the air-conditioning blow-out device as described above, in order to facilitate the fastening work of the screws, the distance between the internal wind direction adjusting plates of the blow-out grill and the distance between the front louvers are set more than necessary. Since it was necessary to set a large value, the mounting screw head could still be seen from the front of the blowing grille inside after installing the air conditioning blowing device, which was still unsatisfactory in terms of appearance.

The present invention has been made for the purpose of solving the above-mentioned problems at the same time, and ensures the easiness of the installation work and the appearance after the installation, and the posture of the housing during the installation work and the wind direction change. It is intended to provide an air conditioning blow-out device for a vehicle, which can reliably hold the air conditioner.

Make them unable to move. At this time, the front end of the upper wall portion may be the second end.
At the same time when the second stop piece is crossed, the second stop piece returns to its original posture due to the elastic force and contacts the front end of the upper wall portion. Therefore, in this state, the upper and lower wall portions are in a state of being sandwiched by the second and first stop pieces, so that the housing cannot be easily rotated.

In this state, the rear wall of the air conditioning case body is applied to the installation portion of the vehicle panel, the driver is inserted through the driver insertion holes arranged in a horizontal state, and the screw is screwed into the vehicle panel to fix the air conditioning case body to the vehicle panel. To do. When the housing is rotated downward after this installation work is completed,
The second stopper rotates forward due to the elastic force to allow the housing to rotate.

When the knob protruding from the front surface of the vehicular air-conditioning blower installed on the vehicle panel is operated to the left and right, all the vertical louvers are simultaneously turned to the left and right via the link. Now, when the housing is rotated downward so that the wind direction is directed obliquely downward, the horizontal louver is directed obliquely downward and the air blown out from the air outlet is directed obliquely downward. At this time, according to the present invention, the rear end of the lower wall portion of the housing comes into contact with the lower surface of the first stop piece of the first rotation position regulating member to regulate further rotation.

When the housing is turned upward so that the wind direction is directed obliquely upward, the horizontal louver is directed obliquely upward so that the air blown out from the air outlet is directed obliquely upward. At this time, according to the present invention, the rear end of the upper wall portion of the housing comes into contact with the upper surface of the second stop piece of the second rotation position restricting member to restrict further rotation.
