PROBLEM TO BE SOLVED: To provide a vehicular driving device that is configured so that prescribed rigidity of a storage case as a whole can be secured while suppressing increase in overall length dimensions in a shaft-line direction of the device.SOLUTION: A bulkhead 90 is provided between a first motor storage part 96 and a second motor storage part 98 of a case member 64, a first branched wall 92 and a second branched wall 94 are provided continuously in the bulkhead 90, and the first branched wall 92 and the second branched wall 94 are connected to each other by connection walls 100 and 102 at two positions separated from each other in the shaft line direction, so as to form a boxy shape part 104 to improve rigidity of the case member 64. In particular, the connection walls 100 and 102 are provided at the two positions separated from each other in the shaft line direction, which can appropriately improve rigidity of a torsion string while suppressing increase in weight. This can reduce reinforcements such as forming a cover member in a curve shape and arranging a rib, and can secure prescribed rigidity of the storage case as a whole while suppressing increase in overall length dimensions in the shaft line direction of a vehicular driving device.SELECTED DRAWING: Figure 2

    【課題】車両用駆動装置の軸線方向の全長寸法の増加を抑制しつつ収容ケース全体として所定の剛性を確保できるようにする。【解決手段】ケース部材64の第1モータ収容部96と第2モータ収容部98との間に隔壁90が設けられるとともに、隔壁90には第1分岐壁92および第2分岐壁94が連続して設けられており、且つ第1分岐壁92および第2分岐壁94は軸線方向へ離間した2位置で連結壁100、102によって連結されているため、箱型形状部104が形成されてケース部材64の剛性が向上する。特に、連結壁100、102が軸線方向へ離間した2位置に設けられるため、重量増加を抑制しつつ捩り系の剛性を適切に向上させることができる。これにより、カバー部材を曲面形状としたりリブを設けたりする補強が緩和され、車両用駆動装置の軸線方向の全長寸法の増加を抑制しつつ、収容ケース全体として所定の剛性を確保できるようになる。【選択図】図2
