PROBLEM TO BE SOLVED: To suppress mass increase of a drive plate, and reduce vibration of a crank shaft.SOLUTION: A vehicular drive device includes: a crank shaft 15 that is rotatably provided in an engine, and in which a plurality of crank pins P1-P4 supporting a connecting rod is formed; and a drive plate 31 that is provided between the crank shaft 15 and a torque converter axially facing the crank shaft, and connects the crank shaft 15 and the torque converter. The drive plate 31 includes a basic constitution part 54, and a plate auxiliary rigidity part 55 having higher rigidity than the basic constitution part. The plate auxiliary rigidity part 55 is provided along a straight line L1 connecting axis centers C1, C2 of at least any one of the crank pins P1-P4 and a rotational center Cx of the crank shaft 15.SELECTED DRAWING: Figure 5 |
