  The inner peripheral wall 21 has a ring shape, and is formed with a diameter increasing from the dial 11 in the meter front direction. That is, the inner peripheral wall 21 covers the connecting portion 32 when the vehicle meter device 1 is viewed from the front.

  The outer peripheral wall 22 has a ring shape and is formed outside the inner peripheral wall 21. The outer peripheral wall 22 is formed to extend in the meter back direction with the end of the inner peripheral wall 21 on the meter front side as a base.

  As shown in FIG. 4, the annular member 20 includes a rib 23, a notch 24, and an engaging claw 25.

  As shown in FIGS. 4 and 7, five ribs 23 are arranged at equal intervals along the circumferential direction of the annular member 20 on the meter back side of the annular member 20.

The three-dimensional index 31 protrudes from the inner side of the inner peripheral wall 21 to the outer side through the notch 24.

Next, the operation will be described.
The operation of the vehicle meter device according to the first embodiment will be described separately as “assembly operation”, “comparison operation”, and “other characteristic operation of the vehicle meter device”.

[Assembly action]
First, the assembly operation of the vehicle meter device 1 will be described. FIG. 9 is an exploded cross-sectional view illustrating the vehicle meter device according to the first embodiment.

  As shown in FIG. 9, the three-dimensional member 30, the dial 11, the light guide plate 12, and the support member 40 are sandwiched and integrated by the inner peripheral wall 21 of the annular member 20 and the engaging claw 25 of the annular member 20. These can be used as the meter subunit 10.

  The meter subunit 10 can be attached to the base member 58 by inserting the bottom claw portion 45 of the support member 40 into the substrate opening 54 of the circuit board 52 and the base opening 59 of the base member 58.

  After the meter subunit 10 is attached to the base member 58, the pointer 61 is inserted into the rotation shaft 56 of the movement 55. Thereby, the assembly of the vehicle meter device 1 is completed.

  That is, the annular member 20, the three-dimensional member 30, the dial 11, the light guide plate 12, and the support member 40 can be unitized.

  For this reason, the annular member 20, the three-dimensional member 30, the dial 11, the light guide plate 12, and the support member 40 can be attached at a time, and the assembly workability is improved.

[Comparison effect]
For example, as shown in FIG. 10, a vehicle meter device in which the top surface 523 a of the rib 523 of the annular member 520 is formed in parallel to the radial direction of the annular member 50 is taken as a comparative example.

  Here, when the annular member is molded by an injection mold, the engagement surface 525a of the engagement claw 525 and the top surface 523a of the rib 523 are undercut. For this reason, in the comparative example, a slide piece that slides radially inward of the annular member 520 is used.

  Then, the engagement surface 525a of the engagement claw 525 of the annular member 520 is formed to be inclined, for example, 20 ° on the meter front side with respect to the radial direction of the annular member 520. On the other hand, the top surface 523 a of the rib 523 of the annular member 520 is formed in the radial direction of the annular member 520.

  As a result, there is no space for accommodating the connecting portion of the three-dimensional member between the rib 523 of the annular member 520 and the dial 11, and there is a problem that a plurality of three-dimensional parts are required.

  On the other hand, in the first embodiment, the three-dimensional member 30 including the dial 11, a plurality of three-dimensional indicators 31 arranged around the dial 11, and a connecting portion 32 that connects the three-dimensional indicators 31, The annular member 20 that covers a part of the three-dimensional member 30 and the support member 40 that is provided on the back side of the dial 11 and supports the dial 11. In the vehicle meter device 1, the annular member 20 includes an inner peripheral wall 21 that covers the connecting portion 32, and an outer peripheral wall 22 provided outside the inner peripheral wall 21. The engaging claw 25 protrudes from the inner peripheral surface to the inner diameter side and engages with the support member 40. The inner peripheral wall 21 extends toward the connecting portion 32 and is provided as a pair with the engaging claw 25. An engagement surface 25a having a rib 23 to be engaged with the engagement claw 25 is formed substantially parallel to the top surface 23a of the rib 23 (FIG. 7).

  Here, the engagement surface 25 a of the engagement claw 25 is inclined 20 ° toward the meter front side with respect to the radial direction of the annular member 20. It is assumed that the top surface 23a of the rib 23 is inclined 20 ° toward the meter front side with respect to the radial direction of the annular member 20. In this case, the engagement surface 25 a and the top surface 23 a are formed by setting the slide direction of the slide piece to a direction inclined 20 ° toward the meter front side with respect to the radial direction of the annular member 20.

  Thereby, a space for accommodating the connecting portion 32 of the three-dimensional member 30 can be provided between the rib 23 of the annular member 20 and the dial 11. For this reason, the three-dimensional member 30 can be made into an integral part, and cost reduction can be aimed at.

  Moreover, the height of the rib 23 of Example 1 can be made lower than the height of the rib of the comparative example. For this reason, generation | occurrence | production of the sink of the design surface (meter front side) of the annular member 20 is suppressed.

  Further, the engaging claw 25 is formed so as to protrude from the inner peripheral surface of the outer peripheral wall 22 of the annular member 20 toward the inner diameter side. For this reason, the engaging claw 25 cannot be seen from the outside. As a result, the decorativeness of the vehicle meter device 1 is improved.

"Other features and functions of vehicle meter devices"
In the first embodiment, the connecting portion 32 has a recess 33 at a position facing the rib 23.

  Thereby, the side surface of the rib 23 of the annular member 20 can be brought into contact with the inner wall of the concave portion 33 of the three-dimensional member 30. For this reason, the three-dimensional member 30 is positioned with respect to the annular member 20 in the circumferential direction of the annular member 20. As a result, the solid index 31 is arranged at a desired position with respect to the dial 11.

  In Example 1, the three-dimensional member 30 is formed of a translucent member, and a plurality of light sources 53 and a plurality of light guide plates 12 that guide light from the light source 53 to the three-dimensional index 31 are provided on the back side of the dial 11. And ribs 23 are provided between the three-dimensional indices 31.

  Thereby, the light irradiated to one solid index 31 is suppressed from being transmitted to another solid index 31 through the connecting portion 32. For this reason, each solid index 31 is made to emit light in different colors.

  In the first embodiment, the bottom surface claw portion 45 is provided on the bottom surface protruding portion 46 and the base member 58 provided with the base display plate 51 is engaged. Thereby, the dial plate 11 can be provided on the meter front direction side from the base display board 51. For this reason, it can be set as the vehicular meter apparatus 1 with the three-dimensional effect which is rich in appearance.

  In addition, a gap can be provided between the bottom surface 43 and the base display panel 51. For this reason, it is possible to make the meter subunit 10 appear to float.
