PROBLEM TO BE SOLVED: To provide an asphalt finisher compatible rear bumper having a simple, light and inexpensive structure and sufficient shock resistance, capable of preventing an air chamber as a driving part from receiving mud or the like, safe and stored compact.SOLUTION: In the load-carrying platform of a load-carrying platform frame 5, a rear bumper 8 is supported by a rotary support 9 so as to jump and move with respect to the load-carrying platform frame 5, the tip of a link arm 6 is fitted to the rotary support 9, the rear bumper 8 is lowered, rotation regulation means 16 is provided to regulate downward rotation with respect to a first arm 6a at a position where the link arm 6 is linear, and the rod 17a of an air chamber 17 as rotary-driving means for refracting the link arm 6 toward the rear part of the load-carrying platform frame 5 by upward rotation is coupled to the rotary-driving shaft 14a of the base end of the first arm 6a. The air chamber 17 is provided at the upper position of the rotary-driving shaft 14a with the rod 17a set down.SELECTED DRAWING: Figure 1

    【課題】簡易で、軽量且つ安価な構造で、十分な耐衝撃性を有し、駆動部であるエアーチャンバが泥等を受けることなく、安全で、かつ、全体をコンパクトに収めることができるアスファルトフィニッシャー対応可能リヤバンパーを提供する。【解決手段】荷台フレーム5の荷台後部で、リヤバンパー8が荷台フレーム5に対して跳ね上げ移動するように回転支持体9をもって支承され、リンクアーム6の先端を回転支持体9に取り付け、リヤバンパー8が下降し、リンクアーム6が直線状になった位置で、第1のアーム6aに対して下方への回転規制手段16を設け、リンクアーム6を上方への回転で荷台フレーム5の後方へ向けて屈折するべく回転駆動手段としてのエアーチャンバ17のロッド17aを第1のアーム6a基端の回転駆動軸14aに結合させるリヤバンパーにおいて、前記エアーチャンバ17はロッド17aを下向きにして回転駆動軸14aの上方位置に設けた。【選択図】図1
