To realize easily and at an inexpensive price a low lift type unmanned carrier which does not cause deterioration in road holding and lift performance.SOLUTION: A vehicle body 4 and a fork body 8 are connected by a pair of link arms 10, 10 and a pair of elastic link arms 12, 12. Thus, the vehicle body 4 can be excellently prevented from being freely tilted between a forward tilt state and a rearward tilt state, with the contact point between a pair of drive wheels 2a, 2a and the ground surface as a fulcrum. The pair of elastic link arms 12, 12 are constituted by a coil spring. Therefore, the frictional force corresponding to interference between the vehicle body 4 and the fork body 8, accompanying the tilting of the vehicle body 4 caused by the length and the arrangement of the pair of elastic link arms 12, 12, can be excellently reduced by the deformation (elongation) of the pair of elastic link arms 12, 12. Thus, the low lift type unmanned carrier which does not cause deterioration in road holding and lift performance can be realized easily and at an inexpensive price.SELECTED DRAWING: Figure 4

    【課題】走行性能およびリフト性能の低下を招くことがないローリフト形無人搬送車を簡単かつ安価に実現すること。【解決手段】車両本体4とフォーク体8とを一対のリンクアーム10,10および一対の弾性リンクアーム12,12によって連結する構成とする。これにより、一対の駆動輪2a,2aと床面との接地点を支点に車両本体4が前傾状態と後傾状態との間で自由に傾動されることを良好に防止できる。なお、一対の弾性リンクアーム12,12は、コイルスプリングにより構成されるため、一対の弾性リンクアーム12,12の長さや配置に起因して生じる車両本体4の傾斜に伴う車両本体4とフォーク体8との干渉に応じた摩擦力を一対の弾性リンクアーム12,12の変形(伸び)によって良好に低減することができる。これにより、走行性能およびリフト性能の低下を招くことがないローリフト形無人搬送車を簡単かつ安価に実現することができる。【選択図】図4
