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 and an automatic transmission 20 in a power transmission path between an engine 14 and drive wheels 16, the torque converter 18 including a rear cover 38 disposed with a plurality of pump blades 40, a turbine 42 disposed with a plurality of turbine blades 44 receiving a fluid flow from the pump blades 40, and a stator 46 disposed with a stator blade 45 disposed between the pump blades 40 and the turbine blades 44, the automatic transmission 20 transmitting power input to an input shaft 48 from the torque converter 18 to a subsequent stage. A release-side flow passage 132 acting as a circulation outward passage allowing fluid to flow toward the inside of the torque converter 18 at the time of a circulation of the fluid in the torque converter 18 is made up of a cylindrical gap 132a between the input shaft 48 and a stator shaft 62.
