The present invention without using an actuator such as a motor or a fluid pressure cylinder, seated person or caregiver of a compact and low-cost to use the power of body weight, yet standing operating auxiliary function with chair work burden is significantly reduced I provide. A chair with standing operation auxiliary function includes a frame 1, a seat panel 3 that is tiltably supported on the frame at the front, contact with Za-ban backside at one end, the contact-sliding contact portion 78 that can be in sliding contact and, and a force application portion 71 footrest that can put your feet on the other end. Moreover, the contact-rotatably supported on the frame between the sliding portion 78 and the foot placing adhesive strength portion, the seat board tilt cam 7 for tilting the seat panel by applying a force to the adhesive strength portion footrest It is provided with a door. .BACKGROUND【課題】モーターや流体圧シリンダ等のアクチュエータを使用することなく、着座者や介助者の体重の力を利用するコンパクトかつ低コストで、しかも作業負担が大幅に軽減される起立動作補助機能付き椅子を提供する。【解決手段】起立動作補助機能付き椅子は、フレーム1と、前部においてフレームに傾動可能に支持された座盤3と、一端部に座盤裏面と接触、摺接し得る接触・摺接部78と、他端部に足を載せることのできる足載せ着力部71とを有する。また、該接触・摺接部78と該足載せ着力部との間において前記フレームに回動可能に支持され、足載せ着力部に力を加えることにより座盤を傾動させる座盤傾動用カム7とを具備する。【選択図】図1
