(Problems to be solved by the invention) However, the manual assembling work requiring such multi-steps is extremely inefficient, and a lot of time is spent on the assembling work of the louver and the connecting rod. Also, when assembling the louver to the housing thereafter, a considerable force is required to deform the housing, and if the shaft end of the louver that is disengaged from the recess is moved within the housing, It is easy to damage the end or scratch the inner surface of the housing.

Therefore, an object of the present invention is to assemble an air outlet device for a vehicle air conditioner, which eliminates inefficiency and breakage between parts caused by a conventional manual work and enables automation of assembly. It is to provide a suitable receiving jig.

(Means for Solving the Problems) In order to achieve the above object, the present invention comprises a frame-shaped housing,
Louvers that are rotatably fitted to a large number of recessed portions formed at predetermined intervals on opposing inner wall surfaces of the housing so that both end shafts thereof are rotatable, and are arranged in parallel in the housing at intervals. And a linking rod that is linked to the housing rear side end of each louver and cooperates with each louver at the same time. The distance between the outer surfaces of the upper end of the frame is smaller than the distance between the inner wall surfaces of the housing, the distance between the outer surfaces of the lower end of the frame is set to be larger than the distance between the shaft ends of the louver, and the connecting rod is attached to the bottom. It has a connecting rod mounting portion for mounting and fixing, and has a frame body that elastically deforms the distance between the inner wall surfaces of the housing to fit the housing on the outer periphery, and is also mounted on the outer periphery of the frame body. Push up the housing from below, A louver having a push-up member for detaching the housing in which the louver and the connecting rod are assembled from the frame body, and having an upper end opened at least at each of the louver shaft end mounting positions on the inner side surfaces of the pair of frame portions having the outer side surfaces. The gist of the invention is that the shaft end insertion groove is formed.

(Operation) When assembling the louver to the housing, first, the sandwiching portion of the connecting rod is placed and fixed upward on the connecting rod mounting portion of the assembly receiving jig according to the present invention. Then, both shaft ends of the louver are inserted into the louver shaft end insertion grooves of the assembly receiving jig, and at the same time, the louver connecting rod attachment portion is fitted into the holding rod of the connecting rod.
A predetermined number of louvers are sequentially connected to the connecting rod. After that, the housing is pushed down from above the receiving jig for assembly, and the receiving jig is fitted into the housing. At this time,
As the housing is pushed into the lower part of the jig, the distance between the pair of inner wall surfaces facing each other elastically deforms and expands, and the lower part follows the outer surface of the receiving jig without the shaft end of the louver touching the inner wall surface. Fit tightly.

When the housing is completely fitted to the receiving jig, the pushing-up member simultaneously pushes up the housing together with a large number of louvers connected by the connecting rod. When the lower end of the housing reaches the upper part of the above receiving jig, the elastically deformed housing returns to its original shape, and at the same time, both shaft ends of each louver automatically move into the corresponding recessed holes formed on the inner wall surface of the housing. And the assembly is completed.
