An improved leg rest hinge structure for a wheelchair that is both strong and easily manipulated. The hinge structure includes a hinge post inversely mounted to a hinge cap which retains the leg tube and foot plate of the leg rest. The hinge post is removably and rotationally inserted into a cylindrical socket fixed to the frame of the wheelchair. A flat land is formed on the exterior circumference of the cylindrical socket that engages either a matching land formed on the underside of the hinge cap or a spring loaded pivot plate fixed on the hinge cap adjacent the hinge post. The structure provides a rugged single post hinge point and an easily manipulated mechanism for releasing the leg rest for rotating it to the side and out of the way.
