Further, when the wind direction control body 60 is rotated and displaced clockwise in FIG. 3, the second side surface (contact portion) 80b of the recess 80 comes into contact with the lower side surface 59b of the support piece 58b (see FIG. Further downward rotational displacement is restricted.
[0018]
In the air blowing device 54 of the present embodiment configured as described above, the outer wall 42 is assembled to the inner wall 44 with the wind direction controller 60 supported by the supports 58, 58 (see FIG. 5), the support pieces 58b, 58b of both supports 58, 58 enter the air conditioning opening 56 as appropriate, and the wind direction control body 60 comes into alignment with the air conditioning opening 56 (FIG. 1). And FIG. 2). The air direction control body 60 is rotationally displaced in the air conditioning opening 56 as described above. For example, when the airflow direction control body 60 is rotationally displaced upward, the temperature control air is blown out and guided to the upper side of the passenger compartment 10, and When it is pivoted downward, the temperature-controlled air is blown out and guided to the rear side (downward side) of the passenger compartment 10 (see FIG. 3). In addition, by displacing the angle of the vertical plate 72 by the lever piece 74, the temperature-controlled air is blown out and guided to the left or right of the passenger compartment 10.
[0019]
[Effect of the embodiment]
Next, the operation of the arrangement structure of the air blowing device according to this embodiment configured as described above will be described. The air conditioning opening 56 is formed at a required position of the wall 42 when the outer wall 42 is formed. A skin material 82 is adhered to the outer surface of the outer wall 42 and the inner surface of the air conditioning opening 56. Further, the supports 58, 58 in the air blowing device 54 are integrally formed at a required position of the inner surface 44 a of the wall body 42 when the inner wall body 44 is formed. In the air guide duct 40 of the embodiment, a total of four air blowing devices 54 are disposed in the longitudinal direction.
[0020]
(Assembly of wind direction control body)
And the wind direction control body 60 separately shape | molded and assembled between the support pieces 58b and 58b of the said support bodies 58 and 58 is attached. At this time, the support pieces 58b and 58b are appropriately elastically deformed in a direction away from each other, and in this state, the wind direction control body 60 is positioned and the support shafts 78 are aligned with the corresponding support holes 62. By releasing the urging | biasing with respect to the support bodies 58 and 58, the support shaft 78 is inserted in each support hole 62. FIG. Thereby, the wind direction control body 60 is pivotally supported between the support bodies 58 and 58 so that rotation is possible.
[0021]

Next, the outer wall 42 formed with the air conditioning opening 56 is positioned and set with respect to the inner wall body 44 to which the wind direction control body 60 is attached, and the screw 52 is interposed between the insertion hole 50 and the screw hole 48a aligned with each other. By tightening, the air guide duct 40 is formed. As a result, the support pieces 58b, 58b of the supports 58 formed on the inner wall body 44 correspondingly enter the air conditioning openings 56 formed on the outer wall body 42, whereby the wind direction control bodies 60 are respectively provided. In the air conditioning opening 56 (see FIGS. 1 and 2). The air guide duct 40 formed in this manner is assembled to the interior front of the passenger compartment 10 together with the integrally formed upper lids 34 and 34 and is configured as a part of the instrument panel 20. The air guide duct 40 is assembled to the reinforcement bar 12 and its air inlet is aligned and connected to the air outlet of the air conditioner unit.
[0022]
(Temperature-controlled air blowing mode)
In the air guide duct 40, when the operation of the air conditioner unit 32 is controlled by the switch operation of the air conditioning operation unit 28 in the instrument panel 20, the temperature-controlled air sent from the air conditioner unit 32 is the air in the duct 40. After passing into the circulation space 46, it moves in the space 46 and reaches the vicinity of each air blowing device 54. The temperature-controlled air flows into the internal space 76 of the hollow case 64 from the air inlet 68 of the airflow direction control body 60 in each air blowing device 54, and then passes between each vertical plate 72 and each horizontal plate 70. The air is blown into the passenger compartment 10 from the air outlet 66 (see FIGS. 1 and 2).
[0023]
In the air blowing device 54 according to the embodiment, when the air direction control body 60 is rotationally displaced and the air outlet 66 is directed upward, the horizontal plates 70 are displaced in the forwardly raised posture accordingly.

Further, when the air direction control body 60 is rotated and displaced in the reverse direction and the air outlet 66 is directed downward, the horizontal plates 70 are displaced in a substantially horizontal posture accordingly. The air is guided to the rear side (indicated by a two-dot chain line in FIG. 3).
[0024]
Note that the wind direction control body 60 is allowed to be rotated and displaced within a required angle range, and the rotation is restricted by the contact between the recess 80 and the support pieces 58b and 58b. Accordingly, since the airflow controller 60 is preferably restricted from being excessively rotated, inefficient blowing of the temperature-controlled air is prevented.
[0025]
Further, if the lever piece 74 is slid to the left side, the front end side of each vertical plate 72 is displaced to the left side in conjunction with this, so that the temperature-controlled air is blown out and guided to the left side of the passenger compartment 10. Further, when the lever piece 74 is slid to the right side, the front end side of each vertical plate 72 is displaced to the right side in conjunction with this, so that the temperature-controlled air is blown out and guided to the right side of the passenger compartment 10.
[0026]
Thus, in the arrangement structure of the air blowing device according to the present embodiment, the support body 58 that is integrally formed with the inner wall body 44 constituting the air guide duct 40 and faces the air conditioning opening 56 from the inside of the air circulation space 46, 58, since the wind direction control body 60 is rotatably supported, a square cylindrical case body that is attached to the air conditioning opening 56 from the outside and supports the wind direction control body 60 is not required, and the number of components is reduced. Is decreasing. In addition, the positioning and arrangement of the wind direction control body 60 with respect to the air conditioning opening 56 is automatically performed by the assembly of the inner wall body 44 and the outer wall body 42, and the assembly work of the air blowing device 54 is simple and easy. Made. Moreover, the wind direction control body 60 is assembled to the supports 58 and 58, and the supports 58 and 58 and the wind direction control body 60 interfere with the skin material 82 attached to the inner surface of the air conditioning opening 56. Therefore, the skin material 82 is not torn or peeled off.
[0027]
In the above embodiment, the case where the arrangement structure of the air blowing device is implemented in the instrument panel 20 is exemplified. However, for example, it is arranged in an air guide duct arranged or formed in an interior member such as a floor console or a ceiling panel. The arrangement structure of the air blowing device according to the present invention can be suitably implemented also for the air blowing device to be performed.
[0028]
【The invention's effect】
As described above, according to the arrangement structure of the air blowing device according to the present invention, the air conditioning opening formed in the first wall body from the inside of the air circulation space is formed in the second wall body integrally formed with the interior member. Since the wind direction control body is rotatably supported on the support body that stands upright, a square cylindrical case body that is mounted on the air conditioning opening from the outside and supports the wind direction control body is unnecessary. Therefore, there is an advantage that the manufacturing cost can be reduced by reducing the number of components. Further, since the positioning and arrangement of the airflow direction control body with respect to the air conditioning opening is automatically performed by the assembly of the second wall body and the first wall body, the assembly of the air blowing device to the air guide duct is simple and easy. It is easy and can streamline the assembly work. And since the skin material stuck on the outer surface of the 1st wall which comprises an interior member was wound and stuck from the inner surface to the rear-end part of the air-conditioning opening provided in this 1st wall, interior member Rutotomoni texture improving is achieved, even tearing or peeling of the said surface skin material due to interference between the skin material and the air-direction control member which is adhered to the inner surface of the air-conditioning openings can be suitably avoided. On the other hand, since the rotational angle range of the wind direction control body is restricted, inefficient blowing of temperature-controlled air due to excessive rotation of the wind direction control body is preferably prevented.
