As for this invention, with connecting means to vertical axis and length and width and height and the below the knee part which have extended from the heel territory to the toe territory and direction of height the support structure of the upper part the elastic foot bottom structure which has extended from (3) and the aforementioned heel territory to the aforementioned toe territory the support structure (2) and the aforementioned upper part (3) and the elastic connection element where the aforementioned foot bottom structure (2) is provided between (10) with, it regards the artificial leg foot which is possessed. When purpose of this invention controls walking to toe separation area comfortably from heel ground, standing the stable feeling it is to offer the artificial leg foot which is given. Because of this object, the support structure of the upper part (3) the foot being almost middle in the length of the self, is connected by the foot bottom structure (2) by the coupling device (4), the coupling device the support structure (3) and the foot bottom structure (2) makes the movement of relative tilt between possible, the case where the patient stands, at least the case of the weight load to the artificial leg foot, the support structure (3) and the foot bottom structure (2) interval between, the coupling device (4) being middle, maintains uniformly.< Selective figure > Figure 1本発明は、踵領域からつま先領域へ延びている縦軸と、長さと、幅と、高さと、下腿部分への接続手段と、高さの方向で上方の支持構造体(3)と、前記踵領域から前記つま先領域へ延びている弾性的な足底構造体(2)と、前記上方の支持構造体(3)と前記足底構造体(2)の間に設けられた弾性的な結合要素(10)と、を具備する義足足部に関する。本発明の目的は、踵接地からつま先離地までの歩行を快適に制御し、立っているときの安定的な感じ与える義足足部を提供することである。この目的のために、上方の支持構造体(3)は、自らの長さにおいて足部のほぼ真中で、連結装置(4)によって、足底構造体(2)に結合されており、連結装置は、支持構造体(3)と足底構造体(2)の間の相対的な傾動の動きを可能にし、患者が立っている際の、義足足部への少なくとも重量荷重の際に、支持構造体(3)と足底構造体(2)の間の間隔を、連結装置(4)の真中で一定に保つ。【選択図】 図1
