The ramp is formed from a carbon fiber-reinforced resin having a longitudinal elastic modulus of 50 GPa or more in the laying direction, the ramp having a connecting portion that connects the plates so that the plates can be divided into two by a plane perpendicular to the plates and parallel to the laying direction, and the connecting portion is formed from a carbon fiber-reinforced resin having a longitudinal elastic modulus of 50 GPa or more in the laying direction. A reinforcing part which forms a plurality of hollow sections arranged in a single row in the laying direction of the plates is arranged in the ramp in an extending manner, the cross section of each hollow section perpendicular to the extending direction is in a trapezoidal shape, the trapezoidal height of the trapezoidal shape of each hollow section is 10-50 mm, the base angle of the trapezoidal shape in contact with the plates is more than 45 degrees and less than 90 degrees, and the height of the trapezoidal shape is 10-50 mm. The width of the face, connected with the plate, of the trapezoid shape is 10-100 mm, and the ramp is formed by connecting the anti-disengaging wheel wall with at least one part of the side end face of the plate and at least one part of the side end face of the hollow section. The invention provides a wheelchair which is light in weight, excellent in load resistance and durability, capable of ensuring rigidity when a load acts on a ramp when a wheelchair user uses the wheelchair, excellent in safety, and capable of coping with a step by being lengthened.
坡道包括架设于阶差或间隙而被使用的可供轮椅行走的板材,由铺设方向的纵向弹性模量为50GPa以上的碳纤维增强树脂形成,坡道具有连接部,连接部以能够以垂直于板材且平行于铺设方向的面将板材分割成两个的方式将板材连接,在坡道中延伸设置有形成在板材的铺设方向上配置成单纵列的多个中空区段的增强部,中空区段的与延伸设置方向垂直的截面的形状为梯形形状,中空区段的梯形形状的梯形高度为10~50mm,梯形形状的与板材相接的底角为45°以上且不足90°,梯形形状的与板材相接的面的宽度为10~100mm,坡道是防脱轮壁与板材侧端面和中空区段侧端面的至少一部分接合而成的。提供轻量、耐载荷性、耐久性优异、能够在轮椅使用者使用时确保载荷作用于坡道上时的刚性且安全性优异,并通过长尺寸化来应对阶差。
