It can follow the shape of the contact surface 43a of each adjustment member 41a.

On the other hand, when changing the position of each receiving surface 25a in order to perform the work of assembling various parts to the base material of another type of door trim, the first electric cylinder 51 is operated as shown in FIG. Each adjusting member group 40 is separated from each receiving member group 20 by displacing each adjusting member group 40 downward. In this state, each receiving member 21 is lowered by its own weight, and the lower surface of the receiving portion 25 contacts the spacer 33 . In this state, the second electric cylinder 61 is actuated to move one of the adjustment members 41a to 41c, for example the adjustment member 41b, to a position facing the lower end 24 of each shaft portion 22 in the vertical direction Y. switch. By operating the first electric cylinder 51 to raise each adjustment member group 40 , each adjustment member group 40 is brought closer to each receiving member group 20 . As a result, the lower end 24 of the shaft portion 22 of each receiving member 21 is brought into contact with the contact surface 43b of the adjusting member 41b after switching, so that the position of each receiving surface 25a in the vertical direction Y is changed to that of the adjusting member 41b. can follow the shape of the contact surface 43b.

Next, the effects of this embodiment will be described.
(1) The jig 10 includes a receiving member group 20 , a supporting member 31 and an adjusting member group 40 . The receiving member group 20 includes a plurality of receiving members 21 each including a shaft portion 22 and a receiving portion 25 provided at an upper end 23 of the shaft portion 22 and having a receiving surface 25a. are arranged as follows. The support member 31 supports each shaft portion 22 so as to be displaceable along the vertical direction Y of the shaft portion 22 . The adjusting member group 40 has contact surfaces 43a, 43b, and 43c, and the lower end 24 is brought into contact with the contact surfaces 43a, 43b, and 43c to adjust the positions of the respective receiving surfaces 25a in the vertical direction Y. , a plurality of adjusting members 41a, 41b, 41c in which the shape change modes of the contact surfaces 43a, 43b, 43c in the parallel direction X of the shaft portions 22 are different from each other.

Further, the jig 10 includes a displacement mechanism 50 that displaces the adjusting member group 40 in the vertical direction Y, and a state in which the receiving member groups 20 are separated from the adjusting member group 40, and the adjusting members 41a, 41b, and 41c are displaced. to the opposite position facing the lower end 24 of each shaft portion 22 in the vertical direction Y.

According to such a configuration, since the above-described effects can be achieved, it is possible to receive a plurality of types of door trims having different shapes.
(2) The fixing member 44 is provided to fix the adjusting members 41a, 41b, and 41c constituting the adjusting member group 40 in parallel in the orthogonal direction Z, and the switching mechanism 60 moves the fixing member 44 in the orthogonal direction Z. By displacing along, one of each adjustment member 41a, 41b, 41c is switched to the opposite position.

According to such a configuration, by displacing the fixing member 44 along the orthogonal direction Z, the adjustment members 41a, 41b, and 41c can be easily switched. In addition, since the adjusting member group 40 may be fixed to the fixing member 44 in a state of being arranged in parallel along the orthogonal direction Z, by rotating the fixing member 44 about the axis extending along the orthogonal direction Z, the adjusting members 41a, 41a The size of the jig 10 as a whole can be reduced compared to the configuration in which 41b and 41c are switched.

(3) A plurality of receiving member groups 20 are provided at intervals in the orthogonal direction Z, and a plurality of adjusting member groups 40 are provided corresponding to each receiving member group 20 .
According to such a configuration, the receiving members 21 are spaced apart in both the parallel direction X and the orthogonal direction Z. As shown in FIG. Thereby, the position of each receiving surface 25a in the up-down direction Y can be set in both the parallel direction X and the orthogonal direction Z. As shown in FIG. Therefore, the door trim can be stably received.

(4) Each receiving surface 25a has a rectangular shape.
In the above configuration, the adjusting members 41a, 41b, and 41c forming the adjusting member group 40 are fixed to the fixing member 44 in parallel in the orthogonal direction Z. As shown in FIG. For this reason, there is a restriction in reducing the interval between the receiving members 21 adjacent to each other in the orthogonal direction Z. As shown in FIG.

On the other hand, the interval between the receiving members 21 adjacent to each other in the parallel direction X can be made smaller than the interval between the receiving members 21 adjacent to each other in the orthogonal direction Z.
In this regard, according to the above configuration, each receiving surface 25a has a rectangular shape, and the long side direction and short side direction of the receiving surface 25a are aligned with the orthogonal direction Z and the parallel direction X, respectively. Therefore, it is possible to reduce the interval between the receiving members 21 adjacent to each other in both the orthogonal direction Z and the parallel direction X and to increase the area of the receiving surface 25a. Therefore, the door trim can be stably received.

<Change example>
For example, the above-described embodiment can be modified and implemented as follows. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

- Instead of the first electric cylinder 51 and the second electric cylinder 61, other actuators such as hydraulic cylinders can be employed.
If the movable plate 35 can be displaced along the vertical direction Y by the first electric cylinder 51, the guide column 52 may be omitted.

- If the fixed member 44 can be displaced along the orthogonal direction Z by the second electric cylinder 61, the rail 36 and the slide member 45 may be omitted.
In order to separate each adjustment member group 40 from each receiving member group 20, even if the first electric cylinder 51 is actuated to displace each adjustment member group 40 downward, the shaft portion 22 of the receiving member 21 does not move to the support member. There is a risk that the receiving member 21 will not be lowered until it abuts against the spacer 33 by being caught on the inner surface of the hole 32 of 31 .

As shown in FIG. 7, a flange 22a is provided between the lower end 24 of the shaft portion 22 and the support member 31, and an urging member such as a compression spring 39 is provided between the support member 31 and the flange 22a. The member 21 can also be biased toward the contact surfaces 43a, 43b, 43c.

According to the above configuration, it is possible to suppress the formation of gaps between the contact surfaces 43a, 43b, 43c of the adjusting members 41a, 41b, 41c and the lower end 24 of the shaft portion 22. FIG. Thereby, the receiving member 21 can be lowered until it contacts the spacer 33 . Therefore, the position of the receiving surface 25a in the vertical direction Y can be matched to the shape of the contact surfaces 43a, 43b, 43c of the adjusting members 41a, 41b, 41c.

- The long side direction of the receiving surface 25a may be aligned with the parallel direction X, and the short side direction may be aligned with the orthogonal direction Z.
- The shape of the receiving portion 25 is not limited to a rectangular plate shape, and other shapes such as a hemispherical shape are also possible.

- In the above-described embodiment, the switching mechanism 60 that switches one of the adjustment members 41a, 41b, and 41c to the opposing position by displacing the fixing member 44 along the orthogonal direction Z was illustrated. The switching mechanism 60 may be configured to switch one of the adjusting members 41a, 41b, 41c to the facing position by rotating the fixed member. In this case, for example, the fixing member 44 is a regular polygonal prism such as a square prism extending along the parallel direction X, and the adjustment member group 40 is provided on each side surface of the regular polygonal prism. Then, the fixing member 44 may be rotated around a rotation axis passing through the centers of the pair of bottom surfaces of the regular polygonal prism.

- The article to be received by the jig according to the present invention is not limited to a door trim, and can be applied to any article.
