The walking aid has a stick body (1) and an under end with a support rod (2) bent away from the main body. Wheels (3,4) lie and both ends and the walking aid may be steered by rotating the stick body, and a tipping mechanism (21) in the area of the wheels brings them towards the main body by rotating about an axis (24). A tipping stopper regulates the external function of the tipping mechanism.
