Abstract
A power transmission apparatus of a hybrid electric vehicle HEV has an engine clutch mounted between a driving motor, which is mounted to a front end of a transmission, and an engine. An internal gear unit, in which an inner gear is enmeshed in an outer gear while the inner gear is inserted into the outer gear, is mounted between the engine clutch and the driving motor, so that an output of the engine is transmitted to the transmission while rotational speeds of the engine and the driving motor are not asynchronous when the engine is coupled.
