The plurality of cylindrical portions 82 i are formed in a cylindrical shape along the depth direction and individually accommodate the plurality of light emitting portions 22. The plurality of passage openings 82j are respectively provided at one end in the depth direction of the plurality of cylindrical portions 82i, and allow light emitted from the light emitting portion 22 to pass as design light constituting the design symbol. The inclined surface 82k is an inclined surface that is provided at the ends of the plurality of tube portions 82i on the side of the plurality of passage openings 82j and is inclined with respect to the reference plane P orthogonal to the depth direction, and a plurality of passage openings 82j are formed. . The dial plate 70 is provided facing the inclined surface 82k and has a transmission window 73b that displays and displays a design symbol by transmitting design light, and displays a plurality of design symbols in one transmission window 73b. The inclined surface 82k has a gap Q between it and the transmission window 73b in the depth direction.

  With this configuration, the vehicle display device 1 cuts off the light of each light emitting unit 22 by the second lamp case 82, so that the vehicle display device 1 is lit and displayed on the transmission window 73 b of the fuel meter 73 as compared with the case where it is cut off by the black print layer of the dial 70 The adjacent space | interval of the bar segment made can be made relatively narrow, and the design property can be improved. Moreover, since the vehicle display device 1 can narrow the lighting display interval of the bar segments, more bar segments can be arranged in the space required in the conventional design. Since the vehicle display device 1 is provided with the transmission window 73b inclined along the inclined surface 82k, the design light (bar segment) can be three-dimensionally displayed on the transmission window 73b. If the vehicle display device 1 has a complicated structure in which the design light (bar segment) is three-dimensionally lit and displayed on the transmission window 73b, there is a possibility that a displacement between the transmission window 73b and the passage opening 82j occurs. The vehicle display device 1 can improve the visibility of the design light (bar segment) by the gap Q between the inclined surface 82k and the transmission window 73b if the transmission window 73b and the passage opening 82j are misaligned. After securing, the edge of the design light (bar segment) can be slightly blurred, and the influence of the positional deviation can be suppressed. As a result, the vehicle display device 1 can appropriately display the bar segment of the fuel gauge 73 that is the design symbol of the dial 70.

  The vehicle display device 1 also includes a positioning hole 78 and a positioning pin 82d that determine the relative position between the dial 70 and the second lamp case 82. The dial plate 70 includes a first instrument display unit 70a and a second instrument display unit 70b. The 1st meter display part 70a is provided in the one side rather than the center part 70c of the said dial plate 70 in the width direction, and displays the speedometer 71. FIG. The second instrument display part 70b is provided on the other side of the center part 70c in the width direction, is configured to include a transmission window 73b, and displays the tachometer 72. The positioning hole 78 and the positioning pin 82d are provided closer to the second instrument display portion 70b than the central portion 70c.

  With this configuration, in the vehicle display device 1, the positioning unit that determines the relative position between the dial 70 and the lamp case unit 80 is provided in the vicinity of the transmission window 73 b of the three-dimensional unit 75 that lights and displays a three-dimensional design symbol. With this configuration, the vehicle display device 1 can accurately align the position of the transmission window 73b of the three-dimensional part 75 that requires a narrower tolerance than the flat part 74 with each passage opening 82j of the second lamp case 82.

  In the vehicle display device 1, the lamp case unit 80 is divided into two parts, and includes a first lamp case 81 and a second lamp case 82. The 1st lamp case 81 is provided facing the 1st meter display part 70a. The second lamp case 82 is provided to face the second instrument display portion 70 b, and each passage port 82 j and positioning pin 82 d are formed, which is different from the first lamp case 81.

  With this configuration, since the lamp case portion 80 is divided into two parts, the vehicle display device 1 suppresses the influence of thermal shrinkage as compared with an integrated lamp case formed of a single resin member as in the prior art. And the tolerance can be narrowed. As a result, the vehicle display device 1 can perform the lighting display without impairing the design in the complicated structure of the three-dimensional unit 75 that performs the three-dimensional lighting display, and at the same time, the planar unit 74 that performs the two-dimensional lighting display. The lit display can be lit without damaging the design. In the conventional integrated lamp case, when the lamp case portion 80 and the dial 70 are formed of different materials, the amount of heat shrink deformation differs, so that a three-dimensional lighting display and a flat lighting display are provided. It is difficult to achieve both. On the other hand, in the vehicle display device 1 according to the embodiment, since the lamp case portion 80 is divided into two, the deformation amount of the heat shrinkage between the lamp case portion 80 and the dial 70 is different. Can also achieve both a three-dimensional lighting display and a two-dimensional lighting display.

[Modification]
Next, a modification according to the embodiment will be described. Although the lamp case portion 80 has been described as being divided into the first lamp case 81 and the second lamp case 82, the lamp case portion 80 may be integrally formed.

  In addition, the inclined surface 82k is an example of the inclination angle and the inclined shape, and is not limited to the above example as long as the inclined surface is inclined with respect to the reference plane P.

  Moreover, although the passage opening 82j demonstrated the example arrange | positioned in a line at predetermined intervals along the circumferential direction of the tachometer 72, it is not limited to this. The passage openings 82j may be arranged in a plurality of rows, or may be arranged at a predetermined interval along a linear direction or the like.

  Moreover, although the design light demonstrated the example made into rectangular shape (bar segment) as a design symbol, it is not limited to this, Another shape may be sufficient as a design symbol.

  Moreover, although the permeation | transmission window 73b demonstrated as a part which displays the remaining fuel of the fuel gauge 73, it is not limited to this, You may display the other information regarding a vehicle.
