  • Description: PROBLEM TO BE SOLVED: To provide a packing constituted by using yarn filled with a plurality of expansion graphite sheet pieces in a cylindrical member capable of assuring a superior sealing characteristic.SOLUTION: A packing is constituted by twisting or braiding a plurality of yarns. Yarn 1 provided with a cylindrical member 6, many expansion graphite sheet pieces 7 formed into a fine elongated shape and the expansion graphite sheet pieces extending in an axial direction of the cylindrical member are filled in the cylindrical member is included in a plurality of yarns. The expansion graphite sheet pieces have one end part 11 in a longitudinal direction formed into a fine extremity end and the other end part 12 in a longitudinal direction formed into a fine extremity end. One end part in a longitudinal direction of the expansion graphite sheet pieces and the other end part in a longitudinal direction of other expansion graphite sheet pieces positioned at the other side in an axial direction of the cylindrical member of the expansion graphite sheet pieces are arranged to be oppositely faced against to each other in a radial direction of the cylindrical member.SELECTED DRAWING: Figure 2 【課題】筒状部材に複数の膨張黒鉛シート片を充填してなるヤーンを用いて構成されるパッキンにおいて、良好なシール性を確保することができるパッキンを提供する。【解決手段】パッキンは、複数本のヤーンがひねり加工又は編組されることによって構成される。筒状部材6を備えるとともに、細長状に形成した膨張黒鉛シート片7を多数備え、前記膨張黒鉛シート片が前記筒状部材の軸心方向に延びるように前記膨張黒鉛シート片を前記筒状部材に装填してなるヤーン1が、前記複数本のヤーンに含まれる。前記膨張黒鉛シート片が、先細形状に形成された長手方向一端部11と、先細形状に形成された長手方向他端部12とを有する。前記膨張黒鉛シート片の長手方向一端部が、この膨張黒鉛シート片の前記筒状部材の軸心方向他方側に位置する他の前記膨張黒鉛シート片の長手方向他端部と、前記筒状部材の径方向に関して対向するように設けられる。【選択図】図2
