(assignment) When moving downhill, there is provided a manual wheeled moving body 10 for manual operation similar to a flat road. (Solution) As a manual wheel movable body 10 which is movable by rotating a wheel manually, The main body upper frame 12 for supporting a heavy object, A pair of traveling wheels, each of which is arranged on each side of the lower frame of the main body that is non-contact with the upper frame 12 of the main body, and whose rotation is freely supported by the first horizontal rotating shaft 16 extending in the width direction of the lower frame of the main body. 18, Each having a pair of abutting rollers 100 attached to the main body upper frame 12 and freely supported by a second horizontal rotational axis extending in the width direction of the main body upper frame 12, Each of the abutment rollers 100 supports the main body upper frame 12, and the first horizontal rotational shaft 16 and the driving wheels relative to the travel wheels so that the rotational force of the abutment rollers 100 can be transmitted to the travel wheels. It is located in the front side of the movable body with a manual wheel 10 rather than the line which connects the contact point N with the road surface of 18, and with the running wheel 18 at the predetermined center angle centering on the 1st horizontal rotating shaft 16. As shown in FIG. Is installed to contact without generating a slip, The load of the heavy material supported by the main body upper frame 12 is not loaded on the first horizontal rotating shaft 16 of the traveling wheel 18, but the contact roller 100 is connected to the contact roller 100 through the pair of contact rollers 100. Is loaded at the contact point N with the corresponding driving wheel, As a result, when the manual wheel-mounted mobile body 10 is on the downward inclined road surface, a pair of forces in the reverse rotational direction are matched with the rotational direction of the traveling wheel 18 in the direction in wh
