PROBLEM TO BE SOLVED: To safely support walking by allowing a user to hold a grip of a walking support device and to travel the device on his/her side.SOLUTION: A walking support device 60 includes: two front wheels 30, 30 having a diameter D1 attached on the advance side of a base frame 2 arranged in a lateral direction; and one rear wheel 50 attached on the opposite side and having a diameter of D2 (>D1). An operation frame 10 having a grip 13 of an operator is attached to the base frame 2 so as to be height-adjustable. First axle supporters 20 where the front wheels 30 are pivotally stopped are loosely attached to the base frame 2, so as to keep the front wheels 30 having contact with a ground surface 62 even when the operation frame 10 is moved by inclination. Axles 28 of the front wheels 30 are positioned on the advance direction side with respect to a tip end 2a of the base frame 2 in the advance direction. A gap 57 is formed above the rear wheel 50 so as to arrange a stopper 58. When the downward pressure is applied from the grip 13, the stopper 58 is abutted to the rear wheel 50 so as to regulate the rotation. When the pressure is canceled, the gap 57 is restored so as to keep traveling.SELECTED DRAWING: Figure 2 |
