To easily correct a positional displacement of a rear axle.SOLUTION: A rear axle attachment structure 1 comprises: chassis frames 11a, 11b; a plurality of rear springs 13a, 13b arranged along the chassis frames 11a, 11b; a center bolt 15 arranged so as to penetrate the plurality of rear springs 13a, 13b, and bundles the plurality of rear springs 13a, 13b; a rear axle 12 having a hole part 12a for accommodating a head part 15a of the center bolt 15; and U-bolts 16a, 16b for fastening and fixing the rear axle 12 to the plurality of rear springs 13a, 13b. The rear axle 12 is regulated in movement in a fore-and-aft direction by the contact of the head part 15a of the center bolt 15 with an internal peripheral face 12x of the hole part 12a, and the head part 15a of the center bolt 15 is constituted so that a position in a fore-and-aft direction is changed by rotation.SELECTED DRAWING: Figure 1

    【課題】リアアクスルの位置ずれを容易に修正すること。【解決手段】リアアクスル取付構造1は、シャシフレーム11a,11bと、シャシフレーム11a,11bに沿って設けられた複数枚のリアスプリング13a,13bと、複数枚のリアスプリング13a,13bを貫通するように設けられ、複数枚のリアスプリング13a,13bを束ねるセンターボルト15と、センターボルト15の頭部15aを収容する孔部12aを有するリアアクスル12と、複数枚のリアスプリング13a,13bにリアアクスル12を締付固定するUボルト16a,16bと、を備え、リアアクスル12は、孔部12aの内周面12xにセンターボルト15の頭部15aが接触することによって、前後方向への移動が規制されており、センターボルト15の頭部15aは、回転することによって前後方向の位置が変化するように構成されている。【選択図】図1
