To provide a front loader attachment and detachment structure, a front loader, and a work vehicle which can facilitate attachment and detachment work to a vehicle body.SOLUTION: A front loader attachment and detachment structure includes: a lock bar 230 swingably supported between a restriction position in which a main frame 100 engaged with a guide 220 is restricted from moving and a restriction release position in which the main frame 100 is allowed to move; an operation lever 250 operable to move the lock bar 230 from the restriction position to the restriction release position against a biasing force; and a detent 240 movably supported between a holding position in which the lock bar 230 is held in the restriction release position and a non-holding position in which the lock bar 230 held in the restriction release position is released. When the lock bar 230 is moved by the operation lever 250 to the restriction release position, the detent 240 is moved by the biasing force to the holding position to be engaged with a recessed portion 231b, and thus the lock bar 230 is held in the restriction release position.SELECTED DRAWING: Figure 6

    【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】ガイド220に係合されたメインフレーム100の移動を規制する規制位置と、メインフレーム100の移動を許可する規制解除位置との間で揺動可能に支持されたロックバー230と、ロックバー230を付勢力に抗して規制位置から規制解除位置へと揺動させるように操作可能な操作レバー250と、ロックバー230を規制解除位置で保持する保持位置と、規制解除位置にあるロックバー230の保持を解除する非保持位置との間で移動可能に支持されたデテント240と、を具備し、デテント240は、操作レバー250によってロックバー230を規制解除位置へと移動させると、付勢力によって保持位置へ移動し、凹部231bに係合してロックバー230を規制解除位置で保持する。【選択図】図6
