PROBLEM TO BE SOLVED: To provide a tread force measurement device that can measure not only pressure on a treading surface by the sole of a walker but also applied state of a force in the direction parallel to the treading surface and that can also measure the distribution of the force.SOLUTION: A tread force measurement device 1 of the present invention includes: rod bodies 2 which are erected in a plurality of places in a manner that the upper end faces are situated on the same plane, with the soles of the walker to be placed on the upper end faces； deformation sensors 3 which measure deformations caused in the rod bodies 2； and an arithmetic unit 4 which calculates compression loads and flexure loads that are imparted to the rod bodies 2 on the basis of the deformations measured by the deformation sensors 3.【課題】歩行者の足裏による歩行面への圧力だけでなく、歩行面に平行な方向の力の掛かり具合を計測することができ、さらにその力の分布も計測できる踏力計測装置を提供する。【解決手段】本発明の踏力計測装置１は、上端面が同一平面上に位置するように複数箇所に立設され、当該上端面に歩行者の足裏が載る棒体２と、この棒体２に生じたひずみを計測するひずみセンサ３と、このひずみセンサ３によって計測されたひずみから、前記棒体２に与えられた圧縮荷重および曲げ荷重を算出する演算装置４とを備えている。【選択図】図１
