Abstract
A folding wheelchair which prevents unexpected unfolding includes an upper support arm and a lower support arm coupling a left side frame and a right side frame foldable in an up-down direction in central portions thereof in a left-right direction. An engaged section is provided in at least one of the upper support arm and the lower support arm. An engagement section engages the engaged section to prevent relative displacement in the up-down direction of the central portions of the upper support arm and the lower support arm in the left-right direction. An operation section switches operation of the engagement section from an engagement state with the engaged section to an unengaged state.
