To transmit motive power from a motor to a driving wheel via a planetary gear device with one rotation element thereof fixed on a fixing member.SOLUTION: A transfer 12 includes a motor 30, a first planetary gear device 24, a second planetary gear device 25 and a connection switching device 40. The transfer 12 is switched between a first mode in which the connection switching device 40 is in an undistributed state with an input shaft 21 directly connected with a rear wheel side output shaft 22, a second mode in which respective rotation elements of the second planetary gear device 25 are connected with the motor 30, the rear wheel side output shaft 22 and a front wheel side output shaft 23 with the input shaft 21 directly connected to the rear wheel side output shaft 22, and a third mode in which the connection switching device 40 is in distributed state with the input shaft 21 connected to a first sun gear S1 of the first planetary gear device 24, the first planetary gear device 24 is in a shift state, and the second planetary gear device 25 is in an integrally rotating state.SELECTED DRAWING: Figure 2 【課題】一つの回転要素が固定部材に固定された状態の遊星歯車装置を介してモータから駆動輪に動力を伝達させること。【解決手段】モータ３０と、第１遊星歯車装置２４と、第２遊星歯車装置２５と、接続切替装置４０と、を備えたトランスファ１２であって、入力軸２１が後輪側出力軸２２に直結された状態で接続切替装置４０が非分配状態である第１モードと、入力軸２１が後輪側出力軸２２に直結された状態で第２遊星歯車装置２５の各回転要素がモータ３０、後輪側出力軸２２、前輪側出力軸２３に連結された第２モードと、入力軸２１が第１遊星歯車装置２４の第１サンギヤＳ１に連結された状態で接続切替装置４０が分配状態であり、第１遊星歯車装置２４が変速状態であり、第２遊星歯車装置２５が一体回転状態である第３モードと、に切り替わる。【選択図】図２
