PROBLEM TO BE SOLVED: To provide a head-up display device which enables a motor portion 16 to be miniaturized and surely suppresses vibration in the thrust direction S of a concave mirror 5. SOLUTION: The head-up display device, which reflects light irradiated from a display unit 2 on the concave mirror 5, has a first shaft part 10a on both sides of the concave mirror 5 and a second shaft part 10b on the opposite side. The first shaft part 10a is connected to an output shaft 16a of a driving motor part 16, while the second shaft part 10b, on which a second spring 15 consisting of plate spring bent into a dog let-shape is attached, is inserted into a second shaft hole 13 of a support part 14. A first spring 19 for absorbing the backlash of the motor part 16 is locked between part of the concave mirror 5 and a locking part 19a at the motor part 16 side. Thereby, a thrust movement of the concave mirror 5 is absorbed by the second spring 15, preventing the generation of noise. COPYRIGHT: (C)2011,JPO&INPIT
