description A muscle strength assisting wheelchair for sensing user input torque by using a polarizing filter is disclosed. The present invention relates to a muscle strength assisting wheelchair including a wheel hub coupled to a rotary shaft, a hand rim coupled to the rotary shaft so as to be positioned outside the wheel hub; and an elastic member connecting the wheel hub and the hand rim, wherein the muscle strength assisting wheelchair includes: a first polarizing filter disposed on the wheel hub; a second polarizing filter disposed on the hand rim so as to face the first polarizing filter, wherein a transmission axis has a predetermined angle difference with respect to the transmission axis of the first polarizing filter; a light source positioned outside the second polarizing filter and emitting light in the direction of the second polarizing filter; and further an optical sensor positioned inside the first polarizing filter so as to face the light source and detecting an amount of light passing through the polarizing filters. 편광필터를 이용하여 사용자 입력 토크를 감지하는 근력 보조 휠체어가 개시된다. 본 발명의 일 구체예에 따른 근력 보조 휠체어는 회전축에 결합하는 휠허브와, 휠허브의 외측에 위치하도록 회전축에 결합하는 핸드림과, 휠허브와 핸드림을 연결하는 탄성부재를 포함하는 근력 보조 휠체어에 있어서, 휠허브에 배치되는 제1 편광필터와, 제1 편광필터와 대향하도록 핸드림에 배치되는 제2 편광필터 - 투과축이 제1 편광필터의 투과축에 대하여 소정 각도 차이남 - 와, 제2 편광필터의 외측에 위치되어 제2 편광필터 방향으로 광을 조사하는 광원과, 광원과 대향하도록 제1 편광필터의 내측에 위치되어 편광필터들을 투과한 광의 광량을 검출하는 광센서를 더 포함한다.
