PROBLEM TO BE SOLVED: To efficiently absorb a shock when a chuck holder is stopped with a small-sized and long life cushioning member. SOLUTION: The chuck holder 7 is rotatably supported on a frame 2 movable inward and outward of a molding machine. The chuck holder 7 is driven by an air cylinder 3, and is stopped at positions for taking out and releasing a molded article by stoppers 16 and 17. In the inside of a rotating locus of the chuck holder 7, cushioning rubber members 24 and 25 are arranged at positions different from the stoppers 16 and 17. Respective cushioning rubber members 24 and 25 for the taking-out position and the releasing position are fitted on a bracket 22 in the opposite directions, and the bracket 22 is fixed on the lower part of the frame 2. Rigid plates 26 and 27 are fixed on the surfaces of the cushioning rubber members 24 and 25, and a roller 28 is supported on the chuck holder 7. Just before the chuck holder 7 is stopped at the releasing position, a roller 28 compresses the cushioning rubber member 25 for the releasing position through the rigid plate 27.
