PROBLEM TO BE SOLVED: To provide a mechanical joint that can splice a butt end of a rebar in a simple configuration without requiring a special structure and a tool.SOLUTION: A mechanical joint S is concerned for splicing butt side ends K1 of multiple rebars K. The mechanical joint S includes a cover member 1, wedge pieces 2 inserted into wedge insertion spaces, and a rotary member 3 for pressing the wedge pieces 2. A pressing part 32 coming in contact or coming close in the outer circumferential point of a minor axis part with multiple wedge pieces 2 disposed between each of the butt side ends K1 and the inner wall of the cover member 1 is rotated. Thereby, the pressing part 32 can displace the pressing part 32 to the press-contacting direction with multiple wedge pieces 2, 2 disposed between each of the butt side ends K1 and the inner wall of the cover member 1 in the outer circumferential point of a major axis part. By this displacement, a distance between the multiple wedge pieces 2 disposed between each of the butt side ends K1 and the inner wall of the cover member 1 is pressed and extended by the pressing part 32.SELECTED DRAWING: Figure 1 【課題】特殊な構造や工具を必要とせず、簡易な構成で鉄筋の突き合わせ端部を継ぐことが可能な機械式継手を提供する。【解決手段】複数の鉄筋Ｋの突き合わせ側端部Ｋ１を継ぎ合わせるための機械式継手Ｓに関する。機械式継手Ｓは、カバー部材１と、楔挿入空間に挿入される楔片２と、楔片２を押圧するための回転部材３とを備える。突き合わせ側端部Ｋ１各々とカバー部材１の内壁との間に配置された複数の楔片２と、短径部の外周点において接する若しくは近接していた押圧部３２を回転させることにより、押圧部３２が、長径部の外周点において、突き合わせ側端部Ｋ１各々とカバー部材１の内壁との間に配置された複数の楔片２，２と圧接する方向へと押圧部３２を変位させることが可能である。この変位によって、突き合わせ側端部Ｋ１各々とカバー部材１の内壁との間に配置された複数の楔片２間の距離を、押圧部３２により押し広げる。【選択図】図１
