PROBLEM TO BE SOLVED: To provide a rise assisting tool that is suitable for a purpose of assisting muscle power in rising without assistance of others, has a simple structure and is suitable for reduction in size and weight.SOLUTION: A rise assisting tool comprises: a thigh part mounting member 3; a lower leg part mounting member 2; a pivotal pin 13 that pivotally supports base ends of both members in a rotatable manner; a torque adjusting gear 11 that is pivotally supported by the pivotal pin 13; a spiral spring 15 that has an inner end fixed to the pivotal pin 13 and has an outer end hooked on a plate surface of the torque adjusting gear 11; a torque adjusting gear driving mechanism that includes a torque adjusting knob 10 and drives rotation of the torque adjusting gear 11 by rotating it; a non-cylindrical stopper convex part that is provided at a tip of the pivotal pin 13; and a pivotal pin stopper concave part that can engage with the stopper convex part on the undersurface of the lower leg part mounting member 2. An axial movement of the pivotal pin 13 makes the stopper convex part detachable from the pivotal pin stopper concave part. 【課題】他人の介助なく立上る際に筋力補助する用途に適し、構造が簡易で小型化・軽量化に適した立ち上がり補助具の提供。【解決手段】立ち上がり補助具は、大腿部着装部材３と、下腿部着装部材２と、両者の基端とを回動自在に軸着する枢軸ピン１３と、枢軸ピン１３に軸支されたトルク調節ギア１１と、内端を枢軸ピン１３に固定し、外端をトルク調節ギア１１板面に掛止した渦巻バネ１５と、トルク調節摘１０を備えそれを回転してトルク調節ギア１１を回転駆動するトルク調節ギア駆動機構と、枢軸ピン１３の先端に設けた非円柱形状のストッパ凸部及び下腿部着装部材２下面のストッパ凸部と嵌合可能な枢軸ピンストッパ凹部とを備える。枢軸ピン１３が軸方向に移動することでストッパ凸部が枢軸ピンストッパ凹部に嵌脱自在に構成されている。【選択図】図４
