ABSTRACT:
A sector is provided with a plurality of pieces divided in a tire circumferential direction, a back segment supporting a plurality of pieces, and an elastic body interposed between end surfaces in the tire circumferential direction of the pieces. In an unheated state before curing, since clearances C1to C3are provided between the piece and the back segment, and the piece is slidable in the tire circumferential direction, it is possible to suitably adjust a gap between the pieces to a uniform state without any deviation. Further, in a heated state at a time of curing, since the clearances C1to C3are reduced by a thermal expansion of the piece, and the piece is fixed to the back segment, the piece does not slide in the tire circumferential direction, and it is possible to prevent an attrition and a galling of the piece from being generated early.
