Abstract: A HUD unit is provided at an upper portion of a meter unit such that a half mirror is positioned in front of a display surface of the meter unit and an upper face of the half mirror is capable of constituting a design face. A support bracket is attached to an instrument panel member supporting an instrument panel. A front end portion of the HUD unit is attached to the support bracket so as to be supported at the support bracket. Accordingly, manufacturing of two different models with or without the HUD unit can be facilitated, driving assist information can be displayed with as less changing of driver's eyes or focus of driver's eye as possible, and a mounting state of the HUD unit can be stabilized.
