Castor type wheels are swivellably mounted at the lower end of the front upright members and the rear upright members are usually connected directly or indirectly to rear wheels of the wheelchair. A joint at the bottom front corner of the side frame comprises a moulded connector having a generally tubular portion which fits over the end of the upright and includes a projecting spigot which fits inside the lower tubular rail. The connector includes a reinforcing web extending between the top of the spigot and the tubular portion and a lower supporting lug. The end of the rail is shaped to fit around and embrace the reinforcing web and the supporting lug.
