To provide a front loader attaching/detaching structure, a front loader and a work vehicle that can facilitate attachment/detachment work to a vehicle body.SOLUTION: A roller 135 rotatably provided on a mainframe 100, and a subframe first lower surface 513, a subframe second lower surface 514 and a subframe third lower surface 515 whose positions can be adjusted are provided, the subframes are provided to a subframe 510 so as to be inclined with respect to a horizontal plane. The mainframe is relatively moved forward so as to be close to the sub-frame 510 when the subframe 510 is mounted on the mainframe 100 and the mainframe 100 moves on the roller 135 while being in contact with the roller 135. As a result, the subframe is adjustable in the vertical position between a subframe side pin 511 and a mainframe side hook 132 and the vertical position between the mainframe side pin 131 and the subframe side hook 522.SELECTED DRAWING: Figure 17

    【課題】車体への着脱作業の容易化を図ることができるフロントローダの着脱構造、フロントローダ及び作業車を提供する。【解決手段】メインフレーム100に回転可能に設けられたローラ135と、サブフレーム510に水平面に対して傾斜するように設けられ、サブフレーム510をメインフレーム100に装着する装着時においてメインフレーム100をサブフレーム510に対して近接するように前方に相対移動させると、ローラ135と当接しながら当該ローラ135上を移動することで、サブフレーム側ピン511とメインフレーム側フック132との上下方向の位置及びメインフレーム側ピン131とサブフレーム側フック522との上下方向の位置を調整可能なサブフレーム第一下面513、サブフレーム第二下面514及びサブフレーム第三下面515と、を具備する。【選択図】図17
