To provide a rear-end collision impact relaxing device for a work vehicle that has high-impact force adsorption capacity using a cushion drum, can be configured to be an inexpensive device and improves the visibility thereof in the night and the like by lighting the whole cushion drum.SOLUTION: A rear-end collision impact relaxing device 14 installed in a rear end of a work vehicle 4 is formed by arranging multiple barrel-shaped cushion drums 13 having a hollow interior in which a water bag is stored. A lighting device is installed on a back side of a lid 16 of the cushion drum 13 and irradiates the water bag with light from the lighting device to light the whole drum.SELECTED DRAWING: Figure 2
【課題】クッションドラムを使用して高い衝撃力の吸着能力で、かつ、安価な装置として構成できるとともに、クッションドラム全体を発光させることで夜間等の視認性を高めることができる作業車両の追突衝撃緩和装置を提供する。【解決手段】作業車両4の後端に設ける追突衝撃緩和装置14を樽型で内部が空洞になっていて内部に水袋を収めたクッションドラム13を複数並べて形成し、クッションドラム13の蓋16の裏側に照明を設け、該照明の光を水袋に照射してドラム全体を発光させる。【選択図】図2
