Abstract: A head-up display apparatus in which display light emitted by a display device to express an image is reflected by a reflecting part, and a virtual image corresponding to the reflected image is displayed. The apparatus includes: a reflecting-part holder provided with a pair of rotary shaft parts protruding at both ends thereof, the rotary shaft parts retaining the reflecting part; a pair of bearings rotatably supporting the pair of rotary shaft parts; and a pair of bearing holders retaining the pair of bearings in a housing; first supported parts protruding in the radial direction of the bearings provided to the bearing holders, and the housing provided with a hole-shaped first support part in which the first supported part of one bearing holder is positioned, and an elongated-hole-shaped second support part elongated in an axial direction in which the first supported part of the other bearing holder is positioned.

Abstract: The present invention addresses the problem of providing a head-up display device having a structure such that the procurement cost of a bezel can be suppressed. A bezel part is integrally formed on a curved wall portion of an upper cover. Since the upper cover is a die-cast product, the curved wall part can be manufactured by one-time casting (die-casting) with a through-hole and the bezel part. Since the bezel part is integral with the upper cover, it is possible to reduce the procurement cost of the bezel part compared to when the bezel part is a separate part. If the bezel is configured as a separate part having a high heatproof temperature, the procurement cost of the bezel increases. However, if the bezel part is formed integrally with the case simply by partially deforming the case, as described in the present invention, it is possible to reduce the procurement cost of the bezel part.

Abstract: A display device includes: a display means that displays a virtual image of a picture by projecting display light representing the picture on a windshield; an identification means that identifies a target outside the vehicle; a control means that causes a first captured image, visually recognized as being superposed on at least a part of the target, to be displayed in the picture; and a vibration detection means that detects the amount of vibration of the vehicle. The control means, when the amount of vibration detected by the vibration detection means exceeds a threshold value, causes a second captured image to be displayed instead of the first captured image. The second captured image is an image of which a color shade difference between pixels configuring an image end and a region outside the image and adjacent to the image end is decreased compared with the first captured image.
