1. An opening and closing body control apparatus comprising:
a motor driving unit that drives a motor to open and close an opening and closing body; and
a control unit that controls an operation of the motor driving unit,
wherein the motor driving unit outputs a predetermined application voltage to the motor, based on a control command from the control unit, and
wherein the control unit is configured to:
when the opening and closing body reaches a first position before a closing-up position, set a target speed of the motor to a closing-up time target speed at which a torque has sufficient force for closing-up the opening and closing body against an upper run channel, and perform feedback control on the motor driving unit, wherein the closing-up position is a position where no gap exists between the opening and closing body and the upper run channel, and
when the opening and closing body reaches a second position closer to the closing-up position than the first position, stop the feedback control, and control the motor driving unit so that the application voltage of the motor at the time of stopping the feedback control is held.
