POWER TRANSMISSION APPARATUS FOR HYBRID VEHICLE

Disclosed is a power transmission apparatus for a hybrid vehicle. A power transmission apparatus for a hybrid vehicle according to an embodiment of the present invention includes a motor housing disposed between an engine and a transmission, at least one motor disposed in the motor housing and connected to a crankshaft of the engine or the transmission, a torsion damper provided in the motor housing, disposed between the engine and the transmission, and having a radially outer side coupled to the at least one motor, a spline hub connected to the torsion damper and configured to transmit driving power, which is transmitted to the torsion damper, to the transmission, and a dust collecting unit disposed in a working fluid flow path through which a working fluid introduced from the transmission passes through the torsion damper and flows toward the at least one motor, installed at a position spaced apart radially outward from the torsion damper based on a radial direction, and configured to collect produced from the torsion damper and contained in the working fluid.
