PROBLEM TO BE SOLVED: To enable lubricating oil to be sufficiently supplied to a lubrication-required place, and furthermore to suppress an agitation loss.SOLUTION: A transfer of a four-wheel-drive vehicle is provided that comprises: an input shaft 110 to which a part of a driving force transmitted to a main driving wheel from a driving source is input; a ring gear 120 for driving a propeller shaft; and a dog clutch 130 which can switch the transmission and block of the driving force between the input shaft 110 and the ring gear 120. The transfer of a four-wheel-drive vehicle further comprises a return spring 150 which acts on the dog clutch and is externally fit onto the input shaft 110. A shim 104 for supporting one end of the return spring 150 is coaxially arranged at the input shaft 110 so as to integrally rotate therewith, the outermost outside diameter D of the shim is larger than the outermost outside diameter d of the return spring 150, and an oil level L of lubricating oil is set so as to be positioned between the outermost outside diameter of the shim 104 and the outermost outside diameter of the return spring 150.SELECTED DRAWING: Figure 6

    【課題】潤滑必要箇所への潤滑油の供給を十分に行うことができると共に攪拌損失を抑制する。【解決手段】駆動源から主駆動輪へ伝達される駆動力の一部が入力される入力軸110と、プロペラシャフトを駆動するためのリングギヤ120と、入力軸110とリングギヤ120との間の駆動力の伝達と遮断とが切り替え可能なドグクラッチ130と、を備え、ドグクラッチに作用するリターンスプリング150が入力軸110に外嵌された4輪駆動車両のトランスファにおいて、入力軸110には、リターンスプリング150の一端を支持するシム104が同軸で、一体回転するように設けられ、シムの最外径Dは、リターンスプリング150の最外径dよりも大きく、潤滑油の油面Lがシム104の最外径とリターンスプリング150の最外径との間に位置するように設定されている。【選択図】図6
