PURPOSE: To surely mount a part on a space part without cracking a chain by providing an amble having a pocket for holding a part between a lower jaw and a vertically movable upper jaw on a holder in such a manner as to be slidable, and also providing a cam part for raising the amble according to the rotation within the track drawn by the amble while the holder is raised from the lying state. CONSTITUTION: A lower jaw 27 is provided on the upper end of a main body 22, and an upper jaw 28 covering the above of the lower jaw 27 is provided on a sub-body 23 to form pockets 19, 19 for nipping a part on left and right parts between both the upper and lower jaws 27, 28, respectively. Further, a claw piece 29 for preventing the escape of the nipped part are provided on the inlet side of the pockets 19, 19, and the claw piece 29 is energized by a third spring 30 so as to be returned upward when lowered. A cam part 31 is provided within the track drawn by the lower end of the main body 22 when an amble 20 is rotated. Since the upper end of the amble 22 is thus passed through the middle of a space part 3 without colliding the end part of the space part 3, the possibility of cracking a chain is eliminated, and the part can be surely mounted on the side edge of the space part. |
