Virtual image display device and attachment device

摘要

A head-up display makes an observer visually recognize an image, which is optically reflected by a combiner, as a virtual image. The head-up display has a main body unit and an attaching unit. The main unit has a light source which is a projection unit for projecting the image. The attachment unit is configured such that the attachment unit can be attached to a sun visor that is provided to a vehicle. The joint member has a rotation shaft that rotatably joints the main unit to the attachment unit. The damper reduces vibration of the main unit in the rotational direction of the rotation shaft. When the rotation shaft of the joint member is attached to the sun visor by the attachment unit, the rotation shaft is substantially parallel to a sun visor supporting shaft so the sun visor can rotate in the direction in which the sun visor opens/closes.
