A power transmission device includes: a power distribution mechanism (20) in which rotation components including a carrier (C1) connected to an engine rotation shaft (11), a sun gear (S1) connected to an MG1 rotation shaft (12), and a sun gear (S2) connected to an MG2 rotation shaft (13) are rotatable in different rotation speeds; a friction clutch (40) which is interposed between an engine (ENG) and the carrier (C1); and a HVECU (50) which performs a stop control for the engine (ENG) and a release control for the friction clutch (40) so as to cause the vehicle to travel only by the power of the second rotary machine (MG2) and performs an engagement control for the friction clutch (40) while the vehicle travels only by the power of the second rotary machine (MG2) so as to perform a push-start of the engine (ENG), wherein the HVECU (50) controls the first rotary machine (MG1) so that the friction clutch (40) is maintained in a half engagement state during the push-start of the engine (ENG).
