However, it goes without saying that the manufacturing cost of the first and second base members 17 and 18 increases when the manufacturing accuracy of the first and second base members 17 and 18 is increased.

Since the first and second flat bars 14 and 15 are manufactured by rolling, the thickness varies in the longitudinal direction, and the variation level is higher than that of the first and second base members 17 and 18. large. Therefore, the inside of the first flat bar 14 has a hole formed in advance around the through hole 19 through which the connecting pin 29 is inserted by counterboring, and one side of the connecting pin 29 has passed through the first flat bar 14. In this state, the retaining ring 32a is attached to the groove 32, and the thickness is adjusted so that the outer side of the first flat steel 14 is in contact with the retaining ring 32a. The same applies to the second flat steel 15.
In the present embodiment, the retaining rings 22, 30a, 31a, 32a, 33a have the same shape and size, and the retaining rings 22, 30a, 31a, 32a, 33a are made common.
