Abstract
Providing a vehicle power transmission device including a hydraulic power transmission device and enabling a shorter entire axial length.A vehicle power transmission device 12 includes a torque converter 18 having a rear cover 38 disposed with a plurality of pump blades 40 and a turbine 42 disposed with a plurality of turbine blades 44 receiving a fluid flow from the pump blades 40, and an automatic transmission 20 transmitting power input to an input shaft 48 from the torque converter 18 to a subsequent stage, in a power transmission path between an engine 14 and drive wheels 16. The turbine 42 is coupled by relatively non-rotatable spline fitting to the input shaft 48 at a position closer to the automatic transmission 20 than the pump blades 40 and the turbine blades 44 in a first axial center C1 direction of the torque converter 18, i.e., at a position closer to the automatic transmission 20 than an outer shell cover of the torque converter 18.
