片２２についても同じである。 Further, the connecting rod 9 or the lifting lever 7 is attached directly to the pivot portion 24. That is, although the pivot part 24 is rotatable, its position when viewed from the side is constant, and therefore, unlike the case of the conventional split configuration in which the connecting block remains in the pivot part, the rotational position of the bearing 20 at the tip of the arm is fixed. There is no need to consider it. When attaching the distal end portion of the arm 7b, the semicircular recess on the distal end surface performs a positioning action with respect to the pivot portion 24, so no separate positioning means is required. This point also applies to the divided piece 22.
