ABSTRACT:
A chassis structure for a mid-wheel drive power wheelchair includes a pair of restricting racks each having a first restricting plate and a second restricting plate. Each restricting plate has a slot at a central portion thereof. A first fixing member is inserted through one end of the first restricting plate and the slot of the second restricting plate, and a second fixing member is inserted through one end of the second restricting plate and the slot of the first restricting plate, so that the two restricting plates overlap to extend and restrict with each other for maintaining a steady and balancing ride.
