A vehicular head-up display device is provided. The vehicular head-up display device includes: a reflector for reflecting display light, which is emitted from a display, to a windshield to display a virtual image; a stepper motor for rotating the reflector and a controller for controlling the stepper motor to control a rotation position of the reflector. When a driver changes a request position of the virtual image to a new position in a direction toward a reset position and the ignition switch is turned off, the controller rotates the stepper motor to change the position of the virtual image to the reset position and thereafter instructs the stepper motor to rotate by a specified angle corresponds to a hysteresis generated at a time of a change in the rotation direction of the reflector between a forward rotation direction and backward rotation direction.
