PROBLEM TO BE SOLVED: To provide a foot part volume measuring instrument capable of more enhancing precision and reproducibility and shortening the measuring time because a water surface wave is easy to generate in a conventional foot part volume measuring instrument and time is required in the attenuation of the water surface wave.SOLUTION: In the foot part volume measuring instrument 1, the cross-sectional shape on the bottom side of an upward opened container 2 is formed into an elongated shape corresponding to the shape of a foot and the cross-sectional shape on the opening side of the container 2 is formed into a shape reduced in an opening cross-sectional area by shortening a tiptoe side 3 while an inclined wall 5 is provided corresponding to an area change between the bottom and opening sides of the container while a water flooding part 7 is provided to the wall on the heel side 4 of the container.COPYRIGHT: (C)2012,JPO&INPIT【課題】従来の足部体積測定器では、水面波が発生しやすく、その減衰に時間が掛かるため、精度と再現性をより高くし、また測定時間を短縮することができる測定器を提供すること。【解決手段】上側を開口した容器2の底面側断面形状を足の形状に対応して細長形状に構成すると共に、開口側断面形状は、爪先側3を短縮させて開口断面積を低減させた形状とし、底面側と開口側間には面積の変化に対応させて傾斜壁5を設け、開口断面積が低減した高さにおいて、踵側4の壁に溢水部7を設けた構成の足部体積測定器1とした。【選択図】図3
