HEAD-UP DISPLAY DEVICE

WIPO Patent Application WO/2023/095898

A1

The purpose of the present invention is to provide a head-up display device that enables a reduction in noise occurring when a mirror is rotated.　This head-up display device comprises: a display that emits display light representing an image; a mirror body part that reflects the display light; a lever part (6) that has a shaft section and a rotational force receiving section (62) and is provided at an end of the mirror body part; a shaft support part (75) that supports the shaft section rotatably about a rotation axis AX; a mirror rotation mechanism that rotates the mirror body part together with the lever part (6) about the rotation axis AX by transmitting rotational force to the rotational force receiving section (62) of the lever part (6); a clamping member (80) that holds the shaft section and the shaft support part (75) in a direction along the rotation axis AX while making the shaft section rotatable with respect to the shaft support part (75); and a low-friction member (90) that comprises a material having a smaller friction coefficient than the clamping member (80), is put between the clamping member (80) and the shaft support part (75), and slides with respect to the shaft support part (75) when the lever part (6) and the mirror body part are rotated.
