PROBLEM TO BE SOLVED: To provide a vehicular transmission device capable of suppressing generation of vibration in a connection pipe even when pulsation of a discharge pressure of an oil pump generates.SOLUTION: A vehicular transmission device includes: an oil pump 40 capable of supplying a hydraulic pressure; a hydraulic pressure control device 50 for regulating a hydraulic pressure supplied from the oil pump 40 and for controlling a drive part 20; and a connection pipe 60 capable of circulating the hydraulic pressure between the oil pump 40 and the hydraulic pressure control device 50. The connection pipe 60 includes: an upstream side pressure receiving surface 61 facing the oil pump 40 side and for receiving the hydraulic pressure from the oil pump 40 side in an oil passage 26; and a downstream side pressure receiving surface 62 facing the hydraulic pressure control device 50 side and for receiving the hydraulic pressure from the hydraulic pressure control device 50 side in the oil passage 26. The pressure receiving area of the upstream side pressure receiving surface 61 is different from the pressure receiving area of the downstream side pressure receiving surface 62.SELECTED DRAWING: Figure 2 【課題】オイルポンプの吐出圧の脈動が生じても、接続管の振動の発生を抑制できる車両用伝動装置を提供する。【解決手段】油圧を供給可能なオイルポンプ４０と、オイルポンプ４０から供給された油圧を調圧し、駆動部２０を制御する油圧制御装置５０と、オイルポンプ４０と油圧制御装置５０との間で油圧を流通可能な接続管６０と、を備え、接続管６０は、油路２６においてオイルポンプ４０側を向きオイルポンプ４０側から油圧を受ける上流側受圧面６１と、油路２６において油圧制御装置５０側を向き油圧制御装置５０側から油圧を受ける下流側受圧面６２と、を備え、上流側受圧面６１と下流側受圧面６２との受圧面積が異なる。【選択図】図２
