The walking aid includes a stick body inclined in the forward-and-backward direction so that the lower end thereof is positioned forward, a support rod installed behind the stick body and inclined so that lower end thereof is positioned backward, and wheels provided on both sides of the lower end of the stick body and on both sides of the lower end of the support rod, steering being carried out by turning the stick body, wherein a rocking mechanism is provided at the wheel installation portion of the stick body to support an axle rotatably with respect to its axis in the forward-and-backward direction. With this kind of structure, even when the stick body is tilted or steered, the axle rocks automatically so that the wheels on both sides remain contact with the ground at all times, whereby it is possible to obtain a stable, easy-to-use walking aid.
