Zusammenfassung:	PROBLEM TO BE SOLVED: To improve power transmission efficiency in a hybrid vehicle.SOLUTION: A power transmission apparatus is provided, mounting a continuously variable transmission 10, in which a primary shaft 11 thereof is coupled to an engine output shaft 15 and to a motor output shaft 41. An output clutch 63 is disposed between an output transmission shaft 57 coupled to a drive wheel and a secondary shaft 12 of the transmission so as to switch these shafts between a coupled state and a released state; and a drive changeover clutch 71 is disposed between the primary shaft 11 and the output transmission shaft 57 so as to switch these shafts between a coupled state and a released state. In a direct coupling mode where the output clutch 63 is released and the drive changeover clutch 71 is coupled, an engine output is transmitted to the drive wheel without passing through the continuously variable transmission 10.
