To provide a rotating body structure which can properly maintain the left-and-right balance of the durability of the rotating body structure even if a mounting form of a transmission to a working vehicle is changed, the transmission and the working vehicle.SOLUTION: In an assembly which is formed by assembling sixth intermediate gears 67A, 67B and needle bearings 116, 117 to a third intermediate shaft 114, the sixth intermediate gear 67A is rotatably supported to the third intermediate shaft 114 via the needle bearings 116, 117, and the sixth intermediate gear 67B is externally fit to the third intermediate shaft 114, and spline-coupled to the third intermediate gear 114. Also, an external shape of the assembly is formed into a left-and-right symmetric shape, and end parts 121A, 121B of the third intermediate shaft 114 are formed into the same shapes.SELECTED DRAWING: Figure 2C 【課題】作業車両へのトランスミッションの搭載態様を変更しても、回転体構造の耐久性の左右バランスを適正に保つことができる、回転体構造、トランスミッションおよび作業車両を提供する。【解決手段】第３中間シャフト１１４に第６中間ギヤ６７Ａ，６７Ｂおよびニードルベアリング１１６，１１７を組み付けてなる組付体では、第６中間ギヤ６７Ａがニードルベアリング１１６，１１７を介して第３中間シャフト１１４に回転可能に支持され、第６中間ギヤ６７Ｂが第３中間シャフト１１４に外嵌されて、第３中間シャフト１１４にスプライン結合されている。また、組付体の外部形状が左右対称に形成されており、第３中間シャフト１１４の端部１２１Ａ，１２１Ｂの形状が同一になっている。【選択図】図２Ｃ
