付機構。 A cylindrical spindle is axially removably inserted into the shell of the hub up to a certain position, and a locking ball is provided at the end of the spindle that is attached to the wheelchair frame so as to be retractable in the radial direction. A control body having a slope for controlling the protrusion and retraction of the locking ball is disposed therein so as to be slidable in the axial direction, and the control body maintains the locking ball in a protruding state. On the other hand, the frame of the wheelchair to which the hub is to be attached is provided with a penetrating portion through which the spindle can pass freely, and the locking ball is kept protruding by the control body, so that the spindle is configured such that the spindle can be detached from the penetrating portion by locking the spindle in the penetrating portion and sliding the control body against the biasing force of the spring to allow the locking ball to enter. A hub attachment mechanism for a wheelchair, characterized by:
