To provide a mast support structure of a forklift in which a peripheral portion of a mast support surface in a front axle is hardly restricted by a space and a mast is prevented from moving in a width direction.SOLUTION: A mast support structure 30 of a forklift includes: a front axle provided in a front part of a vehicle body of the forklift; and a mast 19 including a pair of right and left outer masts 18. The front axle includes mast support parts 38 for supporting lower parts of the pair of right and left outer masts 18. Each of the pair of right and left outer masts 18 includes a fitting part 48 to be fitted to the mast support part 38 through a bush 51. The mast 19 is rotatable around a shaft center P of the front axel. The mast support part 38 has a mast support surface 39 for decomposing a downward load received from the mast 19 into a plurality of directions. The fitting part 48 has a fitting surface corresponding to the mast support surface 39.SELECTED DRAWING: Figure 3

    【課題】フロントアクスルにおけるマスト支持面の周辺部位がスペースの制約を受け難く、かつ、マストが幅方向に移動することを抑制するフォークリフトのマスト支持構造の提供にある。【解決手段】フォークリフトの車体の前部に設けたフロントアクスルと、左右一対のアウタマスト18を備えるマスト19と、を備え、フロントアクスルは、左右一対のアウタマスト18の下部を支持するマスト支持部38をそれぞれ備え、左右一対のアウタマスト18は、ブッシュ51を介してマスト支持部38と嵌合する嵌合部48をそれぞれ備え、マスト19は、フロントアクスルの軸心Pを中心に回動可能であるフォークリフトのマスト支持構造30において、マスト支持部38は、マスト19から受ける下向きの荷重を複数の方向へ分解するマスト支持面39を有し、嵌合部48は、マスト支持面39に対応する嵌合面を有した。【選択図】 図3
