It becomes possible to do. Accordingly, the scales and characters can be illuminated uniformly, thereby improving visibility, and the number of illumination light sources can be minimized without using a light guide plate, resulting in an inexpensive structure.

Further, since the light path is changed so that the light emitted from the illumination light source is directed to the reflection wall portion, the amount of light directed to the reflection wall portion among the light emitted from the illumination light source is increased. Therefore, a lot of light can be diffused by the reflection wall portion, and the illumination space can be efficiently brightened.

Furthermore, since an LED is used, a compact structure can be achieved .

  In the second invention, the light emitted from the illumination light source toward the reflection wall portion is guided to the illumination space on the opposite side of the opposed wall portion with the illumination light source sandwiched by the opposed wall portion. Thereby, light can be collected by the opposing wall portion at the boundary portion of the light diffused by each inclined surface portion, and the uniformity of illumination in the entire illumination space is enhanced.

In the third aspect of the invention, the pointer can be made to emit light using an illumination light source for illuminating the scales and characters formed on the dial. Therefore, it is not necessary to separately add an illumination light source for the pointer, resulting in an inexpensive structure .

  First, the illumination of the speedometer display unit 1b will be described. As shown in FIG. 5, when light is emitted from the LED 41a for the display unit 3a of the speedometer display unit 1b toward the back side of the dial 3, a small amount of light leaking from the notch 25c of the optical path changing wall 25 is removed. Most of the light moves toward the inclined wall 25a of the optical path changing wall 25.

  The light path toward the inclined rod 25a is such that most of the light is reflected by the inclined rod 25a except for a small amount of light passing through the through hole 25d formed in the inclined rod 25a. It is changed to go to.

  Thereafter, the light moving toward the rotation support portion 7 moves while diffusing so as to spread in the vehicle width direction so as to uniformly contact the entire reflection wall portion 22b as shown in FIG. To do.

  Thereafter, the path of the light moving toward the inclined surface portion 22c located on the left side of the opposing wall portion 22d is changed so as to be reflected on the inclined surface portion 22c and uniformly illuminate the left half of the illumination space S2. The path of the light moving toward the inclined surface portion 22c located on the right side of the wall portion 22d is changed so as to be reflected on the inclined surface portion 22c and to uniformly illuminate the right half of the illumination space S2. Further, the light moving toward the opposing wall portion 22d is changed so as to illuminate the optical path changing wall 25 side of the illumination space S2 by the opposing wall portion 22d, and the light whose path has been changed as shown in FIG. Moves between the back surface of the dial 3 and the inclined wall 25a, and illuminates the illumination space S2 located above the optical path changing wall 25.

  As described above, even if the LED 41a is disposed at a position away from the rotation support portion 7 of the pointer 6, the reflection wall portion 22b diffuses the light emitted from the LED 41a, so that the entire illumination space S2 is uniformly illuminated. Is possible. Therefore, the display unit 3a of the speedometer display unit 1b can be illuminated uniformly, thereby improving visibility, and the LED 41a that illuminates the illumination space S2 can be integrated into one without using a light guide plate. Become.

  Further, the light emitted from the LED 41a toward the reflecting wall portion 22b is guided to the illumination space S2 on the opposite side of the opposing wall portion 22d with the LED 41a interposed therebetween by the opposing wall portion 22d. Thereby, light can be collected by the opposing wall part 22d at the boundary part of the light diffused by each inclined surface part 22c, and the uniformity of illumination of the entire illumination space S2 is improved.

  Furthermore, since the light path is changed so that the light beam emitted from the LED 41a is directed to the reflection wall portion 22b, the amount of the light emitted from the LED 41a toward the reflection wall portion 22b is increased. Therefore, a lot of light can be diffused by the reflection wall portion 22b, and the illumination space S2 can be efficiently brightened. Further, the light reflected by the opposing wall portion 22d passes through the space between the inclined flange 25a and the dial 3 without being blocked by the inclined flange 25a, and is opposite to the opposing wall portion 22d across the LED 41a. To the illumination space S2. Thereby, light can be collected in the boundary part of each illumination space S2 illuminated with the light which a pair of inclined surface part 22c each diffused, and the uniformity of illumination of the illumination space S2 whole is improved.

  Next, illumination of the fuel gauge display unit 1c and the water temperature gauge display unit 1d will be described. As shown in FIG. 6, the light emitted from the LED 41 e toward the back side of the dial 3 moves toward the inclined wall 27 a of the optical path changing wall 27. The path of light moving toward the inclined rod 27a of the optical path changing wall 27 is reflected on the inclined rod 27a except for a small amount of light blocked by the light shielding wall 27c, and the fuel gauge display unit 1c in the illumination space S3. Side, water temperature indicator display portion 1d side, and rotation support portion 7 side.

  Thereafter, the light moving toward the rotation support portion 7 moves while diffusing so as to spread in the vehicle width direction so as to uniformly contact the entire reflection wall portion 28a as shown in FIG. To do.

  Thereafter, the path of the light moving toward the inclined surface portion 28b located on the left side of the reflecting wall portion 28a is reflected by the inclined surface portion 28b and uniformly on the left half of the illumination space S3, that is, on the fuel gauge display portion 1c side. The path of the light that is changed to illuminate and moves toward the inclined surface portion 28b located on the right side of the reflecting wall portion 28a is reflected on the inclined surface portion 28b and is the right half of the illumination space S3, that is, the thermometer display portion 1d. It changes so that the side may be illuminated uniformly, and it diffuses so that the fuel gauge display part 1c side and the water temperature gauge display part 1d side of illumination space S3 may be illuminated uniformly.

  Thus, in the illumination space S3, similarly to the illumination space S2, even if the LED 41e is disposed at a position away from the rotation support portion 7 of the pointer 6, the reflection wall portion 28a diffuses the light emitted from the LED 41e. Therefore, the entire illumination space S3 can be illuminated uniformly. Therefore, the display unit 3a of the fuel gauge display unit 1c and the water temperature gauge display unit 1d can be illuminated uniformly, and the visibility is improved, and the LED 41e that illuminates the illumination space S3 without using a light guide plate is combined into one. Since it can, it becomes an inexpensive structure.

  In addition, since the light path is changed so that the light emitted from the LED 41e is directed to the reflection wall portion 28a, the amount of light directed to the reflection wall portion 28a is increased among the light emitted from the LED 41e. Therefore, a lot of light can be diffused by the reflection wall portion 28a, and the illumination space S3 can be efficiently brightened.

  Furthermore, in embodiment of this invention, since LED41a-41f is used, it can be made a compact structure.

  FIG. 7 shows a modification of the embodiment. In this modified example, except that the following points are different from the above-described embodiment, it is configured in the same manner as the embodiment. Therefore, the same components are denoted by the same reference numerals, and detailed description thereof is omitted. . That is, in this modified example, the LED 41b for illuminating the pointer 6 is not provided, but the indicator 6 is illuminated by using the LED 41a for illuminating the scale 3 of the speedometer display unit 1b and the display unit 3a such as characters. ing.

  As shown in FIG. 7, the counter wall 22 d of the meter body 2 is provided with a light passage hole 22 g that penetrates at a position on the printed circuit board 4 side, and light emitted from the LED 41 a toward the rotation support portion 7. Can be passed to the cylindrical portion 24 side.

  Further, a through hole 24a is formed in the cylindrical portion 24 of the meter body 2 at a position facing the light passage hole 22g, and the peripheral wall of the cylindrical portion 24 facing the through hole 24a is formed from the LED 41a. There is provided an inclined portion 24b which is inclined so as to change the path of light emitted through the light passage hole 22g and guided into the cylindrical portion 24 by the through hole 24a toward the pointer 6 side. As a result, part of the light emitted from the LED 41a for illuminating the dial 3 passes through the light passage hole 22g and enters the cylindrical portion 24 from the through hole 24a, and the path is changed by the inclined portion 24b. Then, it moves toward the pointer 6 and enters the pointer main body 62 from the light incident portion 62a.

  Therefore, in this modified example, it becomes possible to cause the pointer 6 to emit light by using the LED 41 a for illuminating the display unit 3 a such as the scales or characters formed on the dial 3, and the LED 41 b is used for the pointer 6. There is no need to add a separate structure, resulting in an inexpensive structure.

In this modification, the application of the speedometer display unit 1b to the pointer 6 has been described, but the structure of the modification may be applied to the pointer 6 of the fuel gauge display unit 1c and the water temperature display unit 1d .

Also, in the present embodiment, the colored portion 3b of the dial 3 was formed by printing or painting black, may be formed in other colors, LEDs 41a, as long as the color which does not transmit light emitted from 41e Good.

  Furthermore, in this embodiment, although application about the vehicle instrument 1 used for a motor vehicle was demonstrated, for example, it may apply to a motorcycle and can also be applied to another vehicle.

  The present invention is suitable for, for example, a vehicle instrument that displays various states of a vehicle by instructions from a pointer.
