PURPOSE:To make it possible to deviate the center of the top piece at the side of parts chucking in relation to the flange at the side of an automatic insertion machine by so providing a shaft as to be capable of tilting due to external force in relation to an upper drum and a lower drum. CONSTITUTION:An automatic aligning bearing 17 is provided to the inner surface of an upper drum 5 to bear the shaft inserted into the automatic aligning bearing on the free tilt. A slider 6 is so fitted to the upper drum 5 as to be able to vertically slide with a spring 13 pressure contacted between the upper drum 5 and the slider 6. The lower end of a shaft 8 is fitted with an automatic aligning bearing 14 through collars 11 and 12. The periphery of this automatic aligning bearing 14 is fitted with the lower drum 7 capable of moving in the direction of right angle cross section to the axis of the slider 6 with balls 13 provided between the periphery of bearing 14 and the slider 6 and with the shaft 8 being capable of tilting in relation to the lower drum 7. The bottom face of the lower drum 7 is fixed with a top piece 9. |
