PROBLEM TO BE SOLVED: To provide an auxiliary wheel mounting structure that enables selection between one wheel traveling and three wheel traveling only by easily machining materials commercially available in home centers.SOLUTION: An auxiliary wheel receiving cylindrical body is provided astride each of left and right body frames 2a, 2b of the rear side of a load receiver and each of left and right leg frames 7a, 7b, and a long caster shaft having auxiliary wheels 16 is detachably fitted and mounted to this. The auxiliary wheels are protruded more than the lower end of the leg frames while the caster shaft is fitted to the auxiliary wheel receiving cylindrical body. Accordingly, this one wheel hand truck enables three wheel traveling in a normal state, and therefore stable traveling is ensured and the burden of a load on a user is reduced. Also, when the traveling ground surface is roughened and uneven, the caster shaft may be removed or the height adjustment is made to enable one wheel traveling.SELECTED DRAWING: Figure 1

    【課題】ホームセンター等で市販されている材料を簡単に加工するのみで、一輪走行と三輪走行の選択が可能な補助輪取付構造を提供する。【解決手段】荷受け台の後方側の左右の各本体フレーム2a、2bと左右の各脚フレーム7a、7bとに跨って補助輪受け筒体を設け、これに補助輪16を有する長尺のキャスター軸を脱着自在に嵌合装着している。補助輪はキャスター軸を補助輪受け筒体へ嵌合装着させた状態で、脚フレームの下端よりも突出している。そのため、この一輪運搬車は通常の状態で三輪走行が可能であり、安定した走行と、使用者への荷重の負担が軽減されることになる。また走行する地表面が荒れていて不陸である場合は、キャスター軸を取り外すか高さ調節して一輪走行するようにすればよい。【選択図】図1
