HEAD-UP DISPLAY DEVICE

摘要

Provided is a head-up display device such that shaking of a display image due to vibration can be mitigated. This head-up display device, which reflects display light output from a display unit with a reflection unit (4) so as to produce an image to be viewed, includes a first supporting part (70) for supporting the reflection unit (4) rotatably about a rotation axis (AX) and a first supported part (60) provided at one end of the reflection unit (4) and supported by the first supporting part (70). The first supported part (60) has a spherical surface formed thereon, and the first supporting part (70) has a sliding surface that is formed therein and is in substantially point contact or line contact with the spherical surface formed on the first supported part (60). A first elastic member (S1) that presses the first supported part (60) and the first supporting part (70) against each other in the rotation axis (AX) direction is provided.
