PROBLEM TO BE SOLVED: To improve the reliability of vehicle body backward movement-halting operation regardless of detection accuracy, detection timing, etc. in a configuration in which the backward movement of a vehicle is halted by detecting an obstacle by an optical sensor and an impact that is often caused by a sudden stop of travel is absorbed.SOLUTION: An anteroposteriorly movable rear bumper 3 is provided at a rear side end of a mower vehicle body 2 for transmission travel via a hydraulic continuously variable transmission 1; if the rear bumper 3 protrudes against an obstacle when the vehicle body 2 moves backward, the rear bumper 3 is pushed and moved to the vehicle body 2 side to absorb an impact force applied on the vehicle body 2, and a trunnion shaft 4 of the hydraulic continuously variable transmission 1 is controlled from the backward movement control position to the neutral position by pushing and moving the rear bumper 3 toward the vehicle body 2.

    【課題】 光学式センサによって、障害物を検出することによって、車両の後進を停止する形態では、検出精度や、検出タイミング等によって、車体の後進停止の作動の信頼性を損いやすく、又、走行を急停止すると、この停止事態によって衝撃を受けることが多い。【解決手段】 油圧無段変則装置1を経て伝動走行するモアー車体2の後側端に、前後移動可能のリヤバンパー3を設け、前記車体2の後進時に前記リヤバンパー3が障害物に突出すると、このリヤバンパー3を車体2の側へ押込移動させて、車体2の受ける衝撃力を吸収すると共に、前記リヤバンパー3の車体2に対する押込移動によって、前記油圧無段変速装置1のトラニオン軸4を後進制御位置から中立位置へ連動制御する。【選択図】 図5
