Abstract

A vehicle display device includes a housing including an opening, an image display device that outputs display light of an image, and a mirror that includes a main body including a reflective surface that reflects the display light toward the opening and is rotatable around a rotation axis. The mirror includes a first and a second ribs that extend along a first direction, and face each other in a second direction. The first rib is formed as a rib closest to a side of the upper end on the back surface, the second rib is formed as a rib closest to a side of the lower end on the back surface, and a central region between the first and the second ribs on the back surface is formed as a flat curved surface, at least a part of which extends from the first rib to the second rib.

Claims (18)

1 . A vehicle display device comprising:

a housing including an opening;

an image display device that is provided in the housing and outputs display light of an image; and

a mirror that is provided in the housing, includes a main body including a reflective surface that reflects the display light toward the opening, and is rotatable around a rotation axis, wherein

the mirror includes a first rib and a second rib, each protruding from a back surface that is a surface of the main body opposite to the reflective surface and extending along a first direction along the rotation axis on the back surface, the first rib and the second rib facing each other in a second direction orthogonal to the first direction,

the back surface includes an upper end that is an end closer to the opening in the second direction and a lower end that is an end farther from the opening in the second direction,

the first rib is formed as a rib closest to a side of the upper end on the back surface,

the second rib is formed as a rib closest to a side of the lower end on the back surface,

a central region between the first rib and the second rib on the back surface is formed as a curved surface, at least a part of which extends from the first rib to the second rib, and

the mirror further including a first end and a second end spaced away from the first end in the first direction, the first rib extending from the first end to the second end.

2 . The vehicle display device according to claim 1 , wherein

an upper end side region formed as a curved surface extending from the first rib to the upper end is provided between the upper end and the first rib on the back surface.

3 . The vehicle display device according to claim 1 , wherein

in the second direction, a surface of the first rib on a side of the opening is inclined so as to be closer to the lower end toward a distal end side of the first rib.

4 . The vehicle display device according to claim 2 , wherein

in the second direction, a surface of the first rib on a side of the opening is inclined so as to be closer to the lower end toward a distal end side of the first rib.

5 . The vehicle display device according to claim 2 , wherein

a lower end side region formed as a curved surface extending from the second rib to the lower end is provided between the lower end and the second rib on the back surface.
