Abstract
A rolling walker 1 comprises a first frame 3 supported by a front caster 2 at both ends thereof and a second frame 5 supported by a rear caster 4 at both ends thereof, and a handle 7 provided to either first frame 3 or second frame 5. The first frame 3 and the second frame 5 are foldably connected each other by a connecting shaft 6. The rolling walker 1 has a closed frame fixing means 11 which fixes the first frame 3 and the second frame 5 in a closed position and connects the first frame 3 and the second frame 5 to stand when the first frame 3 and the second frame 5 are rotationally folded around the connecting shaft 6, so that each frame 3, 5 can be kept folded to stand when the rolling walker 1 is not used. The rolling walker 1 also has a straight moving means 106 which fixes the front caster 2 in a back and front direction of the rolling walker 1 and the front caster 2 is a rotatable caster having the caster rotational axis CF around which the front caster 2 rotates so that all casters 2 and 4 can be fixed in a back and front direction, ensuring straightness in walking.
