To provide a mast support structure capable of suppressing dislocation of a mast pin and a support hole in a vehicle width direction.SOLUTION: In a mast pin support structure 100, a mast attachment part 72 for an axle bracket 70 has a support hole 73 into which the mast pin 60 is inserted and is connected to a mast pin 60 through the support hole 73. An outer peripheral surface 61 of the mast pin 60 is supported by an inner peripheral surface 74 of the support hole 73. The outer peripheral surface 61 of the mast pin 60 and the inner peripheral surface 74 of the support hole 73 have an inclined part 64 inclined so as to gradually separate from a center axis CL as going toward the outside in a vehicle width direction. Thus, the inner peripheral surface 74 of the support hole 73 is supported by the outer peripheral surface 61 of the mast pin 60 at the inclined part 64 even when an external force is applied to the mast attachment part 72 in a direction relatively expanding to a mast 51, thereby suppressing the relative movement of the mast pin 60 and the support hole 73 to a vehicle width direction.SELECTED DRAWING: Figure 4

    【課題】マストピンと支持穴との間の車幅方向における位置ずれを抑制できるマスト支持構造を提供する。【解決手段】マスト支持構造100では、アクスルブラケット70のマスト取付部72は、マストピン60を挿通させる支持穴73を有し、当該支持穴73を介してマストピン60と連結される。マストピン60の外周面61は、支持穴73の内周面74によって支持される。マストピン60の外周面61及び支持穴73の内周面74は、車幅方向の外側へ向かうに従って中心軸線CLから離れるように傾斜する傾斜部64を有する。従って、マスト取付部72がマスト51に対して相対的に広がる方向へ力を受けた場合であっても、傾斜部64において支持穴73の内周面74がマストピン60の外周面61に支持される。これにより、マストピン60と支持穴73との車幅方向への相対的な移動が抑制される。【選択図】図4
