To provide a vehicular drive device for enabling a rotation housing of a fluid coupling to be supported on a case in the axial direction while allowing a variation in the axial size of the rotation housing.SOLUTION: In a vehicular drive device 100 which includes a fluid coupling 5 including a rotation housing 51, and a case 4 including a first support body 41 arranged on one side in an axial direction L with respect to the fluid coupling 5, and a second support body 42 arranged on the other side, there are provided a first support mechanism S1 for supporting the rotation housing 51 in the axial direction L and a radial direction R so as to be rotatable relative to the first support body 41, and a second support mechanism S2 for supporting the rotation housing 51 in the axial direction L and the radial direction R so as to be rotatable relative to the second support body 42. At least either between the rotation housing 51 and the second support mechanism S2 in the axial direction L or between the second support mechanism S2 and the second support body 42 in the axial direction L, an elastic member 10 is arranged having elasticity in the axial direction L.SELECTED DRAWING: Figure 2
