PROBLEM TO BE SOLVED: To provide a low constant speed travel device for truck enabling the truck to perform a low speed/constant speed travel in an easy and stable manner in compliance with a work promoting speed without requiring any high-level operation technique.SOLUTION: This invention provides a low constant speed travel device 7 comprising: a pair of right and left oscillation frames 11 attached to a lower part of a truck loading space swingably backward and forward with respect to a frame 9 fixed and connected to a loading space chassis 8; a pair of right and left rotating wheels 12 that are supported at free ends of the pair of right and left oscillation frames 11 and can be moved to or away from outer peripheral parts of both right and left rear wheels 5 of the truck through forward or backward oscillation of the oscillation frames 11; motors 13 for driving the pair of right and left rotating wheels 12; and a cylinder 14 changing-over between one state in which the pair of right and left rotating wheels 12 are press-contacted with the outer peripheral surfaces of both the right and left rear wheels 5 of the truck to enable the truck to travel and the other state in which the pair of right and left rotating wheels 12 are spaced apart from both the right and left rear wheels 5 of the truck to release a transferring of the driving rotational force of the rotating wheels 12 to both the rear wheels 5.SELECTED DRAWING: Figure 3

    【課題】運転に高度なテクニックを要することなく、作業進行速度に合わせて容易かつ安定よく微速・定速走行させることができるトラックの微定速走行装置を提供する。【解決手段】トラックの荷台下部に、荷台シャーシー8に固定連結された枠フレーム9に対して前後に揺動可能に取り付けられた左右一対の揺動枠体11と、該左右一対の揺動枠体11の自由端部に支持されて揺動枠体11の前後揺動によりトラックの左右両後輪5の外周部に接離可能な左右一対の回転輪12と、これら左右一対の回転輪12を駆動するモータ13と、左右一対の回転輪12をトラックの左右両後輪5の外周面に圧接させて走行を可能にする状態と左右一対の回転輪12をトラックの左右両後輪5から離間させて該回転輪12の駆動回転力の両後輪5への伝達を解除する状態とに切替えるシリンダ14と、からなる微定速走行装置7を装備させている。【選択図】図3
