The distance l ₁ between the outer surfaces of the support walls 1a, 4b is set to be slightly smaller or almost equal to the distance l ₂ between the inner surfaces of the support walls 1a, 1a, and
4a are superimposed so that each of the pivot shafts 4c, 4c is inserted into each of the through holes 1b, 1b up to the outer surface thereof.

When one of the single bodies 4a, 4a is inserted into the through hole 1b and set, the inner side of the pivot portion 4b of the set side single body 4a is opposite to the inner side. The distance l ₃ from the inner surface of one of the supporting walls 1a to the inner surface of the pivot portion 4b of the non-set side unit 4a is
The distance _l4 to the tip of c is set to be slightly larger or almost equal to the distance l4.

When supporting the link member 4 on the support member 1 in this way, one unit 4a of the link member 4
As shown by the solid line in FIG.
In this state, the other non-set side unit 4a is set at an angle of about 90 degrees with respect to the set side unit 4a, so that the inner surfaces of the pivoting parts 4b, 4b of each unit 4a, 4a are overlapped with each other. The non-set side unit 4a is completely inserted between the set side unit 4a and the support wall 1a,
