PROBLEM TO BE SOLVED: To provide a frame structure capable of reducing its weight and material cost while ensuring predetermined strength, and a wheel chair.SOLUTION: A frame structure 100 comprises: a pair of side part frames 110 having seat parts 111, back parts 112 curved upward from the rear parts of the seat parts 111, and leg parts 113 curved downward from the front parts of the seat parts 111; and a pair of support frames 120 which extend forward and backward below the pair of side part frames 110 and support the pair of side part frames 110 from below by direct or indirect connection of its front ends and rear ends to the side part frames 110. Caster holding parts 123 for mounting casters 12 are provided at the front ends of the support frames 120. Main wheel holding parts 124 for mounting main wheels 11 are provided at the rear ends of the support frames 120. The support frames 120 are formed in a tapered shape so as to be tapered from the rear ends toward the front ends.SELECTED DRAWING: Figure 2 |
