The upper surface α of the business trip portion 71 b of the rear lower member 7 becomes a cylinder portion upper surface 5 a ₁ projecting from the tube port 51 of the cylinder upper portion 5 a of the lower cylinder 5 toward the vehicle rear side, and is supported substantially horizontally by the bearing 81 here. Further, the support shaft 82 is provided.

  The seal member 91 is an annular packing made of foam, and is interposed when the main cylinder port 51 of the lower cylinder 5 is joined to the lower end cylinder port 11 of the upper cylinder 1. Reference numeral 92 designates a secondary seal member, and a secondary pipe (not shown) that leads to both sides of the instrument panel after the front defroster nozzle in which the upper cylindrical body 1 and the lower cylindrical body 5 are integrated is assembled to the vehicle body. The lower end tube port is interposed when the sub tube port 52 is joined.

  Next, a front defroster nozzle formed by assembling the lower cylinder 5 and the upper cylinder 1 configured as described above will be described. For example, the upper cylinder 1 is integrally attached to the lower cylinder 5 as follows. The support shaft 82 of the lower cylinder 5 is inserted into the cutout groove 42 of the upper cylinder 1, and the upper cylinder is rotatably attached to the lower cylinder.

  Prior to assembly, as shown in FIG. 2, the seal member 91 is attached to the main cylinder port 51 at the upper center of the lower cylinder 5, and the sub seal material 92 is attached to the sub cylinder port 52. Then, as shown in FIG. 6 (a), the lower cylinder 5 is arranged so that the lower air intake 50 is horizontal. The upper cylinder 1 is lifted obliquely upward and forward, and the projecting portion 45 is arranged rearward. Subsequently, the upper cylinder 1 is tilted downward to guide the protruding portion 45 so as to pass through the support shaft 82 as shown in FIGS. 2 and 6 (a) (the business trip between the support shaft 82 and the rear plate portion 70). Part 72b). The support shaft 82 is inserted into the cutout groove 42 of the upright piece 4 where the protruding portion 45 has finished submerging the support shaft 82. It can be said that the notch groove 42 provided in the standing piece 4 of the movable upper cylindrical body 1 is fitted into the support shaft 82 of the fixed lower cylindrical body 5.

  Specifically, the upper cylindrical body 1 is directed rearward and tilted downward as indicated by a straight arrow in FIG. At the stage where the projecting portion 45 finishes diving the support shaft 82 and the portion of the notch groove 42 immediately after that comes into contact with the support shaft 82, the upper cylindrical body 1 is moved around the notch groove 42 as shown by the curved arrow in FIG. Turn backwards. As a result of this turning, the support shaft 82 is guided deeply into the cutout groove 42 formed in an inverted C shape from the groove opening 42a (b in FIG. 6). Even if there is a constricted portion 42b that is smaller than the shaft diameter of the support shaft 82, the upper cylindrical body 1 is a resin molded product having flexibility. By such a turning operation, the groove of the constricted portion 42b is supported by the support shaft 82. Push the width wide. By holding the upper cylinder 1 in a hand and turning while pressing backward, the support shaft 82 passes through the constricted portion 42b relatively easily and reaches the arc-shaped depression 42d. A support shaft 82 is inserted into the arc-shaped recess 42d of the cutout groove 42, and a front defroster nozzle is obtained in which the upper cylinder 1 is rotatably attached to the lower cylinder 5 (FIG. 7).

The distance from the arc-shaped depression 42d to the lower end cylindrical port 11 of the upper cylindrical body 1 and the main cylindrical port 51 of the lower cylindrical body 5 from the support shaft 82 is set to be the same. Both cylinder ports 11 and 51 of the cylinder 5 are matched. As shown in FIG. 8, a front defroster nozzle is provided in which a support shaft 82 is disposed on the groove bottom 42c with the groove 42a of the cutout groove 42 facing upward.
On the other hand, when the upper cylinder 1 is tilted down, the protruding portion 45 hits the lower cylinder 5 and the subsequent tilting is prevented. Therefore, the upper cylindrical body 1 is regulated and becomes a front defroster nozzle that cannot be moved back further. In the present embodiment, when the upper cylinder 1 is tilted in the range of more than 45 ° and less than 75 ° rearward from the standing state, the protruding portion 45 is the flange of the main tube port forming portion 71 of the lower cylinder 5 at the stage shown in FIG. It hits the part 71a. At this stage, the front defroster nozzle is configured to stop the upper cylinder 1 from turning.

  The front defroster nozzle configured as described above is provided with a notch groove 42 in the upper cylinder 1, while a support shaft 82 is provided in the lower cylinder 5, and the support shaft is inserted into the notch groove 42. Since 1 is rotatably attached to the lower cylinder 5, the assembly of the front defroster nozzle is facilitated. The upper cylinder 1 is pivotably attached to the lower cylinder 5 and the upper cylinder 1 is brought forward so that the cylinder ports 11 and 51 of the lower cylinder 5 are combined, so that the assembly of the front defroster nozzle is easy. become. In particular, when assembling to the vehicle, since the upper cylinder 1 is rotated around the support shaft 82 of the lower cylinder 5, both the cylinder ports 11, 51 are matched easily and without error. The support shaft 82 and the upright piece 4 responsible for the rotation function are stable in shape, and the assembly locus to the vehicle is made constant, so that work efficiency can be improved. Unlike the integral hinge of Patent Document 1, it is useful for automating the assembly of a front defroster nozzle to a vehicle by a robot or the like.

  Further, the projecting portion 45 hits the lower cylindrical body 5 due to the backward tilting of the upper cylindrical body 1, and the subsequent tilting is prevented there, so that the upper cylindrical body 1 is not completely tilted and this bites into other parts and other parts. And will not damage other sealing materials. Nevertheless, since the upper cylindrical body 1 protruding above the front defroster nozzle is maintained in a tilted state, it does not interfere with the door frame DR. As shown in FIG. 7, the robot can be transported from the door frame DR of the front door to the vehicle compartment without being interfered with the door frame DR, and can be easily assembled to the vehicle body.

In addition, as shown in FIG. 7, the upper cylinder 1 is inclined backward in the state where the protruding portion 45 is engaged with the lower cylinder 5, and the groove 42 a of the notch groove 42 fitted to the support shaft 82 is placed on the lower side. Since the main body load of the upper cylindrical body 1 is applied downward, the action of narrowing the groove opening 42a of the notch groove 42 works. The notch groove 42 is conveniently fitted into the support shaft 82 so that the upper cylinder 1 can be detachably attached to the lower cylinder 5, but may be detached. However, particularly in the case where the front defroster nozzle is transported into the passenger compartment, the form shown in FIG. 7 is adopted, not only to avoid the interference of the door frame DR, but also the upper cylinder 1 and the lower cylinder by narrowing the groove 42a. Promote strong integration with 5. This front defroster nozzle has a really reasonable structure for improving workability and safety.
As shown in FIG. 8, even a unit or the like in which the lower cylindrical part LP for the central blower outlet and the side blower outlet is integrated with the front defroster nozzle can easily and reliably enter the vehicle interior without interfering with the door frame DR. Can be transported. The lower cylinder 5 bottom air inlet 50 of smoothly connected to the discharge port AC ₁ of the air conditioner unit AC. Reference numeral RB denotes an engaging projection with the lower cylinder 5 protruding from the lower cylinder part LP.

  Then, after the lower cylinder 5 is attached to the vehicle body, if the upper cylinder 1 is raised, the assembly locus thereof is constant, so that the lower end cylinder port 11 coincides with the upper end cylinder port 51 of the lower cylinder 5. By inserting the locking rod 25 and the locking claw 26 into holes such as the dash panel dp, the assembly of the front defroster nozzle to the vehicle is completed smoothly. Then, an instrument panel is mounted and the blower outlet 10 aligns smoothly with the opening part KA.

Furthermore, the upper cylinder 1 and the lower cylinder 5 are separate from each other, and both parts are reduced in size without being bulky, so that the mold size can be reduced and the mold cost can be greatly reduced. The front defroster nozzle of Patent Document 1 has a large molding die because the upper part and the lower part are connected by an integral hinge, but in the present invention, the upper cylinder 1 as the upper part and the lower cylinder 5 as the lower part are separated. The mold size is halved. By reducing the size of the bulky front defroster nozzle to the upper cylinder 1 and the lower cylinder 5, it is possible to reduce the cost of transportation and parts.
Furthermore, unlike the front defroster nozzle that has been manufactured for each individual vehicle model, the lower cylinder 5 is shared and separated as a common part, so that the parts (lower cylinder 5 ) Can be made common, and the cost can be reduced unprecedented.

In addition, since the groove width of the cutout groove 42 is gradually narrowed in a reverse letter C shape from the upper surface of the upright piece 4 downward, when the upper cylinder 1 is attached to the lower cylinder 5 The support shaft 82 is guided deeply into the cutout groove 42 from the groove opening 42a, so that the upper cylinder 1 can be easily attached to the lower cylinder 5. Further, the projecting portion 45 makes it easier for the support shaft 82 to dive, leads the portion of the notch groove 42 to the support shaft 82, and makes it easier to integrate the upper cylinder 1 and the lower cylinder 5.
On the other hand, since the lower end cylindrical port 11 of the upper cylindrical body 1 is in a horizontal state and the notch groove 42 is provided downward from the upper surface 41 of the upright piece 4, once the support shaft 82 is inserted into the notch groove 42, It becomes difficult for the upper cylinder 1 to come off. The front defroster nozzle of FIG. 8 assembled in the vehicle has the support shaft 82 disposed on the groove bottom portion 42c with the groove 42a of the cutout groove 42 facing upward, so that the support shaft 82 can be moved even when there is vertical vibration during vehicle travel. It functions as a stopper to prevent the upper cylinder 1 from coming off. By forming the constricted portion 42 b in which the groove width of the notch groove 42 is smaller than the shaft diameter of the support shaft 82, the upper cylinder 1 is more difficult to come off.

Also, the upper cylindrical body 1 can be removed from the front defroster nozzle in which the two are integrated by exchanging parts or the like, by pushing the tip of the protruding portion 45 downward, the mouth of the notch groove 42 is opened by the lever principle. The removal at that time is very easy. Not only is the replacement of the upper cylinder 1 or the lower cylinder 5 partly cheap, but the repair and replacement thereof can be carried out smoothly.
Thus, the front defroster nozzle exhibits a number of excellent features.

  The present invention is not limited to those shown in the above embodiments, and various modifications can be made within the scope of the present invention depending on the purpose and application. The shape, size, number, and the like of the upper cylinder 1, the front upper member 2, the rear upper member 3, the lower cylinder 5, the front lower member 6, the rear lower member 7, the seal member 91, and the like can be appropriately selected according to the application. . For example, in the front defroster nozzle of the embodiment, the projecting portion 45 abuts against the flange portion 71a of the main tube opening forming portion 71 due to the backward tilting of the upper cylindrical body 1, and then the tilting is prevented. Of course, it may hit the other part of the body 5, and it will of course be prevented from falling behind.
