A body frame (10) for a wheelchair includes a main frame (11), a back frame (12) and a seat frame (13). The body frame (10) includes hinge structures (31), (38), (53) and (56) for causing the user of a wheelchair to lie down, and cross braces (15) and (16) for implementing the fold of the wheelchair. The hinge structures (31), (38), (53) and (56) are provided so that the main frame (11) and the seat frame (13) are divided in a longitudinal direction. The center of each of the hinge structures (31), (38), (53) and (56) is present on an identical virtual axis in a transverse direction. The cross braces (15) and (16) are disposed before each of the hinge structures (31), (38), (53) and (56).
