A power transmission device for a hybrid vehicle includes: a power distribution mechanism including a plurality of rotation components; a friction engagement device which is interposed between the engine and the rotation component connected to the engine; and a control device which performs a stop control for the engine and a release control for the friction engagement device so as to cause the vehicle to travel only by the power of the second rotary machine and performs an engagement control for the friction engagement device while the vehicle travels only by the power of the second rotary machine so as to perform a push-start of the engine, and the control device controls the first rotary machine so that the friction engagement device is maintained in a half engagement state at a differential rotation speed higher than a predetermined rotation speed during the push-start of the engine.
