PROBLEM TO BE SOLVED: To repeatedly apply pressing force to concave parts while increasing and decreasing the same around foot parts abutting on pushing parts by the front face pushing part, the back face pushing part, and the side face pushing part using the spring force of the spring acting member for pressing even though the fastening force of the restricting member for attaching a knee cover to the foot parts is reduced by solving problem that the pushing force to the pressure points becomes zero when a fastening margin becomes zero that the disadvantage of the conventional expandable knee supporter.SOLUTION: A plurality of the restricting members constituted by attaching pushing members in which the pushing parts are erected in the inside face thereof memorize either one of the state stretching the knee and the state bending the knee and is attached to either one of the spring action member for pressing the front face side constituted by attaching the pushing members in which the pushing parts are erected in the inside face and the spring acting member for pressing the back face side, the pushing force repeatedly increasing and decreasing to each of the pressing points present in the leg part front face, back face, and side feces in the pressing parts by the tension force of the restricting member generated by the flexion of either one of the spring acting member for pressing front face side and the spring acting member for pressing the back face side generated by the knee bending exercises.COPYRIGHT: (C)2012,JPO&INPIT【課題】従来の伸縮可能な膝サポーターの欠点である締付代がゼロになるとツボの押圧力がゼロになる問題を解決して、膝カバー部材を脚部に取付ける拘束部材の締着力が減少しても、加圧用ばね作動部材のばね力を利用して、表面押圧部、裏面押圧部、側面押圧部で当接する脚部周囲の窪み部(ツボ)に押圧力を繰り返し増減して加える。【解決手段】押圧部を立設した押圧部材を内面に取付けた複数の拘束部材を、膝を伸ばした状態、又は、膝を曲げた状態のいずれかを形状記憶し、押圧部を立設した押圧部材を内面に取付けた表面側加圧用ばね作動部材、又は、裏面側加圧用ばね作動部材のいずれかに取り付け、膝の屈伸動作で生ずる表面側加圧用ばね作動部材、又は、裏面側加圧用ばね作動部材のいずれかの撓みで生ずる拘束部材の引張力で、脚部表面、裏面、側面に存在する各ツボに押圧部で繰り返し増減する押圧力を加える。【選択図】図1
