PROBLEM TO BE SOLVED: To achieve an auxiliary vehicle for non-powered light work, having versatility, further high safety and excellent convenience in use.SOLUTION: This vehicle is not put in the movable state by an oil actuator 103 provided below a seat 101 and stored in an air or a coiled spring as far as a user 100 does not sit on the seat 101, and the movable state follows the opening and closing degree of the oil actuator 103 provided below the seat 101 and stored in the air or the coil spring. A traveling brake hydraulic-coupled to the actuator is always controlled to prevent scudding of the akinetic power auxiliary vehicle for light work and lessen users moving burden. In this structure, the user 100 also puts his feet on the ground and moves up and down to apply his body weight to the seat 101, or leaves the seat or moves in the direction of leaving the seat, further in addition to this, moves in the direction of horizontally bending to move in combination with the steering operation, whereby the three-dimensional looper-like movement and the steering operation can be achieved.COPYRIGHT: (C)2013,JPO&INPIT【課題】軽量で汎用性があり、また安全性が高く使い勝手に優れた軽作業用補助車を実現すること。【解決手段】座席101下に設けたエアもしくはコイルバネ中に収容されている油アクチュエータ103により使用者100が座席101に着座しない限り、可動状態とならず、またその可動状態は座席101下に設けたエアもしくはコイルバネ中に収容されている油アクチュエータ103の開閉程度に追従し、これと油圧結合した走行ブレーキを常に制御することによって無動力軽作業補助車の逸走を防ぐとともに使用者の移動負担を軽減する。併せて使用者100が地面に足をついて上下動して体重を座席101にかけたり、離席ないし離席方向に動いたり、更にこれに加えて水平曲折方向に動いて操向動作と組み合わせて動く事により、立体尺取り虫運動と操向動作とを生かし得る構造とする。【選択図】 図1
