To provide a seat inclination angle changing device for a wheelchair which can set a tilt angle of a seat surface finely according to the taste of each user, and which is easy to operate by an interlocutor and a wheelchair equipped with this device To do.SOLUTION: The seat surface inclination angle changing device 1 for a wheelchair is provided with:A ground part 4 which can be raised and lowered with respect to the frame 20 and can be fixed at an arbitrary position, a rod 3 to which the ground part 4 is fixed at the lower end, and a rod 3 penetrating the frame 20 And a cylindrical body 2. The frame 20 is provided with a handle 26, and by operating the lever 8 of the handle 26, the rod position fixing means 7 can be actuated and released.The front wheel 40 is brought into contact with the ground so that the rear wheel 30 is separated from the ground,The rod position fixing means 7 is releasedThe ground portion 4 is lowered to bring it into contact with the ground, and at that positionThe rod position fixing means 7 is actuatedIt is possible to change the inclination angle of the seat surface by fixing so that the grounding part 4 does not rise and fall.Selection2【課題】それぞれの使用者の好みに合わせて細かく座面の傾斜角度を設定することができ、介添者の操作が容易な車いす用の座面傾斜角度変更装置及びこの装置を取り付けた車いすを提供すること。【解決手段】車いす用の座面傾斜角度変更装置1は、フレーム20に対して上昇降下可能で、任意の位置で固定可能な接地部4と、接地部4が下端に固定されている棒体3と、棒体3が貫通した状態でフレーム20に取り付けられている筒体2とを有する。フレーム20には、ハンドル26が設けられ、ハンドル26のレバー8を操作することで、棒体位置固定手段7の作動及び解除できる。前輪40を地面に接触させて後輪30を地面から離間させ、棒体位置固定手段7を解除し接地部4を降下させて地面に接触させ、その位置で棒体位置固定手段7を作動させて接地部4が上昇降下しないように固定して、座面の傾斜角度を変更できる。【選択図】 図2
