PROBLEM TO BE SOLVED: To suppress a gear rattling sound without deteriorating fuel economy by adding a damper and suppress a transfer device from being enlarged in size while improving durability of the damper.SOLUTION: In a transfer device for a vehicle, a coupling 20, a drive gear 14 and a damper 30 are provided on an output shaft 12 for a rear wheel, where an input-side connection part 22b of the coupling 20 is connected to an inner periphery part of the damper 30 through a first spline fitting part S1, and a power transmission member 81 through which power is transmitted from the damper 30 to the drive gear 14 is connected to the input-side connection part 22b of the coupling 20 through a second spline fitting part S2, allowing relative rotation within a prescribed angle. The first spline fitting part S1 and the second spline fitting part S2 are arranged adjacent to each other in a shaft direction on the output shaft 12 for a rear wheel, so that a structure in which power is transmitted from the damper 30 to the drive gear 14 and the second spline fitting part S2 can be arranged to be parted into opposite sides in the shaft direction of the power transmission member 81.SELECTED DRAWING: Figure 2

    【課題】ダンパの追加により燃費を悪化させることなく歯打ち音を抑制し、かつダンパの耐久性の向上を図りながら、トランスファ装置の大型化を抑制する。【解決手段】車両のトランスファ装置は、後輪用出力軸12上に、カップリング20とドライブギヤ14とダンパ30とが備えられ、カップリング20の入力側連結部22bがダンパ30の内周部に第1スプライン嵌合部S1を介して連結されると共に、ダンパ30からドライブギヤ14に動力を伝達する動力伝達部材81がカップリング20の入力側連結部22bに第2スプライン嵌合部S2を介して所定角度の相対回転を許容して連結される。第1スプライン嵌合部S1と第2スプライン嵌合部S2とが後輪用出力軸12上の軸方向に隣接させて設けられることで、ダンパ30からドライブギヤ14への動力伝達構造と、第2スプライン嵌合部S2とが、動力伝達部材81の軸方向の反対側に振り分けて配置できる。【選択図】図2
