A walking aid apparatus including a movable body and a support unit provided to the movable body to support a user further includes means for reducing a change rate of speed of the movable body with respect to a change in a force applied from the user to the support unit. With this arrangement, even when the user stumbles and applies a strong force to the support unit, the movable body can be prevented from moving suddenly, minimizing the possibility of the user being left behind the movable body.
