Claims (1)
の少なくとも一方に段部を形成し、この段部に隣り合う
セグメントの一部を重畳状態にして複数のセグメントを
環状に配設してなるシール部材であって、各セグメント
の前記段部側側面にはピンが突設され、一方シール部材
本体段部にはこのピン係合用の穴が形成されており、こ
のピンを係合川穴に係合させることにより各セグメント
をシール部材本体に取り付けてなるパイプ水圧試験機用
シール部材において、前記各セグメントはセグメント重
畳部において互いにシール部材円周方向に相対的摺動可

用シール部材。A step part is formed on at least one of the edges of the inner circumferential surface of the seal member main body which is ring-shaped and made of an elastic body, and a plurality of segments are arranged in an annular shape with some of the segments adjacent to the step part overlapping each other. A pin is provided protruding from the side surface of the stepped portion of each segment, and a hole for engaging the pin is formed in the stepped portion of the main body of the seal member. In a sealing member for a pipe hydraulic testing machine, in which each segment is attached to a sealing member main body by engaging with the sealing member, the segments are connected to each other at a segment overlap portion so as to be relatively slidable in the circumferential direction of the sealing member. A sealing member for a pipe hydraulic testing machine characterized by the following.
