PROBLEM TO BE SOLVED: To provide a sheet stopper with which a sheet-like material can be easily and reliably fixed to a pipe member by clipping the sheet-like member without partially extending and/or breaking the sheet-like material.SOLUTION: The sheet stopper clips the sheet-like material to fixedly fit it up with the pipe member so as to fix the sheet-like material to the pipe member, is provided with a body part where an opening part made by notching a part of the peripheral wall of a cylinder in an axial direction to be opened is formed, and is structured as follows: the sheet-like material and the pipe member are introduced through the opening part and the inner peripheral surface of the body part clips the sheet-like material to fixedly fit it up with the pipe member； and a plurality of recessed parts are formed on the inner peripheral surface of the body part.【課題】シート状物を部分的に伸ばしたり破ったりすることなく、しかも容易かつ確実にシート状物を挟んでパイプ部材に固定可能なシート止め具を提供すること。【解決手段】シート状物を挟んでパイプ部材に嵌着させることにより、シート状物をパイプ部材に固定するためのシート止め具であって、円筒の周壁の一部を軸方向に切り欠いて開口させた開口部を形成した本体部を備え、前記開口部からシート状物及びパイプ部材を導入して本体部の内周面がシート状物を挟んでパイプ部材に嵌着するようになされ、前記本体部の内周面には、複数の凹部が形成されているようにした。【選択図】 図１
