PROBLEM TO BE SOLVED: To provide a propeller curve surface shape recording tool capable of securing an intensity of each contact element even when the number of contact points is increased in the tool for recording the shape of a propeller surface by contact with the propeller surface by a plurality of contact elements at multiple contact points.SOLUTION: Two or more rotary elements 11 comprising plate bodies are arranged in series so as to be superposed with upper end parts at 2 or more positions, and a link part is provided rotatably about a rotational axis perpendicular to the plate surface in the superposed portions, and include: a gauge body in which a contact part is formed by a bent edge part or an angle part of the rotary element 11; a propeller fixing part 30 formed in a fixable manner at a center of the propeller; and a connected body fixed with the rotary element 11 on one end side and fixed with the propeller fixing part 30 on the other end side and formed with the contact part on the propeller surface so that the contact part can come into contact with the propeller surface when the propeller fixing part 30 is fixed to the propeller.SELECTED DRAWING: Figure 1 【課題】複数の接点要素によりプロペラ表面に多接点で接触することでプロペラ表面の形状を記録する器具において、接点数を増やしても各接点要素の強度を確保することができるプロペラ曲面形状記録具を提供する。【解決手段】板体からなる回転要素１１を２以上端部同士で重なるように直列に配置し、重なった部分において板面に垂直な回転軸回りに回転可能に連結したリンク部が設けられ、回転要素１１の曲縁部又は角部により接触部が形成されるゲージ体と、プロペラの中心に固定可能に形成されたプロペラ固定部３０と、一端側に回転要素１１が固定されるとともに他端側にプロペラ固定部３０が固定され、プロペラ固定部３０をプロペラに固定したときに前記ゲージ体の前記接触部が前記プロペラ表面に接触可能に形成される連結体とを有する。【選択図】図１
