Claim:
1. A walking assistance device comprising: a base body; a driving unit configured to move the base body; a distance detection unit configured to detect a distance from the base body to a user; a control unit configured to control the driving unit based on a result of determination that at least the user is too close to the walking assistance device, the determination being made by comparing the distance detected by the distance detection unit with a predetermined value for determination; a safety distance range setting unit configured to set, as a safety distance range, a distance range from the base body to the user during safe walk of the user; a walking state determination unit configured to determine whether or not the distance detected by the distance detection unit is out of the safety distance range; and an inclination detection unit configured to detect inclination of a road surface on which the walking assistance device travels, wherein controlling the driving unit by the control unit based on the result of determination that at least the user is too close to the walking assistance device includes controlling the driving unit by the walking state determination unit when the distance detected by the distance detection unit is determined to be out of the safety distance range; and the safety distance range setting unit is configured to set the safety distance range based on the inclination detected by the inclination detection unit.
