Zusammenfassung:	To provide an inner surface joint device which enables reduction of the risk to a worker when the inner surface joint device is broken.SOLUTION: An inner surface joint device (1) includes: a first contact jig (12) which contacts with an insertion port side end surface of an existing pipe; a chain (30) which is connected to the first contact jig and applies tensile force, acting in a direction where a joint pipe is joined to the existing pipe, to the joint pipe to be joined to the existing pipe; and an auxiliary chain (14) which restricts movement of the chain if connection between the chain and the first contact jig is released.SELECTED DRAWING: Figure 1 【課題】内面接合装置が破損した場合に作業者に及ぶ危険性を低減可能な内面接合装置などを実現する。【解決手段】内面接合装置（１）は、既設管の挿し口側の端面に当接する第１当接治具（１２）と、第１当接治具に連結され、既設管に接合される接合管に対して既設管と接合される方向の張力を加えるチェーン（３０）と、チェーンと第１当接治具との連結が解除された場合におけるチェーンの移動を制限する補助チェーン（１４）と、を備える。【選択図】図１
