PROBLEM TO BE SOLVED: To provide a lightweight foot pressure detector with novel structure, having excellent maneuverability, and capable of stably achieving high detection accuracy by reducing influence of hardness, irregularity, and temperature of a floor on a detection result.SOLUTION: A foot pressure detector 10 is so configured that a sensor body 12 for detecting a foot pressure of a subject, is disposed on a base plate placed on the floor. The sensor body 12 includes an elastic part formed of an elastic material, and is configured to detect the foot pressure of the subject on the basis of elastic deformation of the elastic part. Further, an upper face of the base plate on which the sensor body 12 is superposed is defined as a flat surface and the base plate is defined to have a heat insulation structure with a space.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】軽量で取り回し性に優れると共に、床の硬さや床の凹凸、床の温度の検出結果への影響を低減して、高い検出精度を安定して実現することができる、新規な構造の足圧検出装置を提供すること。【解決手段】被検者の足圧を検出するセンサ本体12が床に置かれる基板上に配設された構造を有する足圧検出装置10において、センサ本体12が弾性材料で形成された弾性部を備えており、弾性部の弾性変形に基づいて被検者の足圧が検出されるようになっている一方、センサ本体12が重ね合わされる基板の上面が平面とされていると共に、基板が空間を有する断熱構造体とされている。【選択図】図3
