The invention provides a vehicle drive transmission device capable of controlling gear noise to be small. A vehicle drive transmission device (100) is provided with: a gear mechanism (1) provided in apower transmission path connecting a drive power source (MG) and a pair of wheels; a housing (2) having a first reservoir for storing oil and housing the gear mechanism (1); and a storage part constituting member (6) that is disposed above the first accumulation part and constitutes a second accumulation part that accumulates oil. A gear mechanism (1) is provided with: gears (32, 42, 43); shaft members (31, 41) connected to the gears; and bearings (91, 92, 93, 94) that rotatably support the shaft members (31, 41) with respect to the housing (2). The housing has a bearing support part (24) forsupporting the bearing. The storage part constituting member has a first contact part (61) that contacts the bearing support part (24) via a first elastic member (71) having elasticity.
本发明提供能将齿轮噪声控制为较小的车用驱动传递装置。车用驱动传递装置(100)具备被设置于连结驱动力源(MG)与一对车轮的动力传递路径的齿轮机构(1);具有存积油的第一存积部并收纳齿轮机构(1)的壳体(2);及被配置于比第一存积部靠上方并构成存积油的第二存积部的存积部构成部件(6)。齿轮机构(1)具有:齿轮(32、42、43);与该齿轮连结的轴部件(31、41);以及相对于壳体(2)将轴部件(31、41)支承为能够旋转的轴承(91、92、93、94)。壳体具有支承轴承的轴承支承部(24)。存积部构成部件具有经由具有弹性的第一弹性部件(71)与轴承支承部(24)抵接的第一抵接部(61)。
