Abstract

Provided is a vehicular power transmission device that is provided with a hydraulic power transmission device, and that is able to have a shorter overall length in the axial direction. The vehicular power transmission device is provided with a transaxle case (22) that is divided by a partition (68) provided to the reverse side of a torque converter (18) from an engine (14) and that has: a first chamber (R1) that houses the torque converter (18); and a second chamber (R2) formed on the reverse side of the partition (68) from the torque converter (18). The first chamber (R1) and second chamber (R2) are isolated from each other in an oil-tight fashion by means of an oil seal (70) that, in an oil-tight manner, seals the gap between the inner peripheral surface of a through-hole (69) formed in the partition (68) and the outer peripheral surface of a tube-shaped pump drive shaft (58). A first thrust bearing (94) is disposed between a starter (46) and a side-wall section that is at the partition (68) side of a rear cover (38). The first thrust bearing (94) is provided in a manner so that a portion overlaps with the oil seal (70) in a view from a direction perpendicular to a first shaft center (C1).

Description

technical field [0001] The present invention relates to a structure of a power transmission device for a vehicle constituting a part of a power transmission path between an engine and drive wheels. Background technique [0002] There is known a power transmission device for a vehicle that includes a torque converter in a power transmission path between an engine and drive wheels, wherein the torque converter includes: an input-side rotary member provided with a plurality of pump vanes; a plurality of turbine blades output-side rotary members of the fluid flow of the pump blades; and a stator blade provided with a stator blade arranged between the pump blades and the turbine blades. For example, Patent Documents 1 to 4 describe such vehicle power transmission devices.
