PROBLEM TO BE SOLVED: To provide a mast device capable of grounding a tip part of a fork to a ground surface even when a tilt device is not equipped therewith, and a fork lift equipped with the mast device.SOLUTION: A fork 5 is provided with: a shank part 50 which is supported by a lift bracket 4 to extend in a vertical direction; and a blade part 51 which projects in a horizontal direction X separating from the lift bracket 4 from a lower end of the shank part 50. A lower face of the blade part 51 inclines obliquely upward toward the tip. The lift bracket 4 is provided with: a slot 46 which extends obliquely upward to the horizontal direction X; and a shaft 45 to which the shank part 50 is attached, and which is inserted into the slot 46 so as to be movable along the slot 46. When the lift bracket 4 is lowered, a rear end of the blade part 51 is grounded to the ground surface, and when the lift bracket 4 is further lowered, the shaft 45 moves from the lower end toward an upper end of the slot 46. Thus, the fork 5 inclines forward.SELECTED DRAWING: Figure 4

    【課題】ティルト装置がなくてもフォークの先端部を地面に接地させることができるマスト装置、及び、該マスト装置を備えるフォークリフトを提供する。【解決手段】フォーク5は、リフトブラケット4に支持されて上下方向にのびるシャンク部50と、シャンク部50の下端からリフトブラケット4に対して離間する水平方向Xに突出するブレード部51と、を備え、ブレード部51の下面は先端に向けて斜め上向きに傾斜している。リフトブラケット4は、水平方向Xに対して斜め上向きにのびる長穴46と、シャンク部50が取り付けられ、長穴46に沿って移動可能に長穴46に差し込まれたシャフト45とを備える。リフトブラケット4が下降すると、ブレード部51の後端部が地面Fに接地し、さらにリフトブラケット4が下降すると、シャフト45が長穴46の下端から上端に向けて移動する。それによって、フォーク5が前傾する。【選択図】図4
