1. A motor control device for a working vehicle, comprising:

  • a rotational speed control device that controls a rotational speed of a motor in accordance with an operation amount of an accelerator pedal;

    a travel drive device that transmits rotation of the motor to wheels through a torque converter and a transmission;

    a speed ratio detection device that detects a speed ratio of an input shaft and an output shaft of the torque converter; and

    a speed restriction device that restricts a maximum rotational speed of the motor in accordance with a speed ratio detected by the speed ratio detection device, wherein;

    the speed restriction device restricts the maximum rotational speed when a detected speed ratio is in an acceleration region of the rotational speed of the motor to less than the maximum rotational speed when a detected speed ratio is in a non-acceleration region.
