Zusammenfassung:	To provide an open shield machine capable of preventing or reducing unexpected sinking of the open shield machine and easily adjusting an excavation depth.SOLUTION: A support device that supports an open shield machine main body against a ground surface when the open shield machine main body moves along the ground surface comprises: an abutting tool that moves in contact with an abutment surface which is either the ground surface or a surface of a support supported on the ground surface, and transmits at least a part of the gravity of the open shield machine main body to the ground surface; and displacement means that displaces the abutting tool relative to the open shield machine main body in a direction having a vertical component.SELECTED DRAWING: Figure 3 【課題】オープンシールド機の不意の沈下を防止又は減少させることができると共に掘進深さを簡単に調節できるオープンシールド機を提供する。【解決手段】オープンシールド機本体が地表面に沿って移動する際にオープンシールド機本体を地表面に対して支持する支持装置であって、地表面又は地表面に支持された支持物の表面のいずれかである当接面に当接して移動し、オープンシールド機本体の重力の少なくとも一部を地表面に伝える当接具と、オープンシールド機本体に対して当接具を、鉛直方向の成分を有する方向に相対的に変位させる変位手段と、を備えてなる、支持装置である。【選択図】図３
