In a hybrid vehicle having a locking mechanism in which a play elimination process is required in the locking, a torque shock in the play elimination is reduced. In a hybrid vehicle 1 having a locking mechanism 700 which is a cam-lock type engaging apparatus, an ECU 100 performs MG1 locking control. In the control, play is formed between a cam 710 and a clutch plate 720 of the locking mechanism 700. The formed play is gradually reduced such that the torque shock in the play elimination does not occur due to the phase control of the cam 710, on the basis of an initial value of the amount of the play when the clutch plate 720 is bought into contact with a friction part 733 and a play elimination amount G.
