    • In application of a square wave voltage to a motor MG2 to make the motor MG2 output a torque equivalent to a torque command Tm2*, the procedure of square wave control corrects reference phases ψb and −ψb as phases for maximizing an absolute value of the output torque of the motor MG2 with a rotational position detection error θerr and sets the results of the correction to an upper limit phase ψul and a lower limit phase ψll of the square wave voltage (step S110). A target voltage phase ψ* is set within a phase range defined by the upper limit phase ψul and the lower limit phase ψll, in order to reduce a torque difference between the torque command Tm2* and a torque estimate Tm2est (steps S120 and S130). An inverter 42 is controlled based on the target voltage phase ψ* and a rotational angle θ of the motor MG2.

    • A seat back comprises a support bracket in which a stay of a head rest is inserted, a guide bracket for supporting a rear surface of a vertically intermediate portion of the support bracket on the seat back frame, a head rest tilt mechanism, and a pressure receiving member which moves rearward when pushed by the body of an occupant. The head rest tilt mechanism includes slotted brackets each having a guide hole and slide members which individually movably engage the respective guide holes of the slotted brackets along the longitudinal direction thereof. The head rest tilt mechanism drives the sub-frame so that the head rest body tilts forward while moving upward as the slide members are moved upward along the guide holes when the pressure receiving member is moved rearward.
