PURPOSE:To enhance the working efficiency of assembling work, etc., by bending a rubber tube to easily and accurately attach the same to a ring member. CONSTITUTION:After a rubber tube 6 is inserted in a holder 15 through an outer ring 7, a piston rod 13 is extended to displace respective clamping pawl parts 16 to the outside of the diameter direction of the tube 6 and the rubber tube 6 is pressed and fixed to the inner peripheral surface of the holder 15 and one end part 6A of the rubber tube 6 is expanded to the outside in the diameter direction thereof by respective expanding pawl parts 21. By extending the piston rod 24B of a folding-back cylinder 24 in this state, the rubber tube 6 is inserted in the expanding pawl parts 21 along with the outer ring 7 and one end part 6A is folded back on the upper end side of the outer ring 7 to be attached to the outer ring 7. |
