PROBLEM TO BE SOLVED: To materialize a retainer ring of a structure getting in parallel with a taper surface at an end part of a pneumatic rubber and receiving contact pressure with wide area and a pneumatic rubber product provided with the same. SOLUTION: The retainer ring 6 has a plurality of concentrically arranged annular bead wires 61 arranged in an axial direction. At this time, diameter of the annular bead wire 61 is made gradually smaller from one side to another side of the axial direction. The retainer ring 6 is formed with the annular bead wire 61 laminated on concentric circles, the bead wire 61 of the upper layer is arranged at the maximum diameter part of the bead wire 61 of the lower layer. Consequently, an inner surface of the retainer ring 6 is formed in a taper shape. COPYRIGHT: (C)2007,JPO&INPIT
