Specifically, the shift position is displayed in the case of the speedometer 6a, and the remaining amount of fuel is displayed in the case of the tachometer 6b.

  In the present embodiment, since the basic configuration of the holding unit 20 corresponding to each of the speedometer 6a and the tachometer 6b is the same, the holding unit 20 described above represents the holding unit 20 corresponding to the speedometer 6a. I will explain.

  As shown in FIG. 2, the holding portion 20 includes a cutout portion 20 a in which the peripheral wall 2 b of the facing member 2 is cut out in a U shape, and a protruding portion that protrudes from the outer edge of the cutout portion 20 a toward the inside of the facing member 2. 20b and a cylindrical portion 20c that is connected to the vehicle occupant side of the protruding portion 20b. The protrusion 20b is formed in a U shape along the outer edge of the notch 20a.

  The cylindrical portion 20c is formed in a substantially cylindrical shape that opens to the vehicle occupant side and the side away from the occupant of the shielding wall 2a. As shown in FIGS. 2 to 4, the cylindrical portion 20 c rotates the center of the indicator portion 10 a of the dial plate 10, that is, the rotation of the pointer 11 when the facing member 2 is arranged on the passenger side of the moving body of the dial plate 10. It is arranged at a position corresponding to the center. Further, the cylindrical portion 20c is provided with a locking portion 21 that protrudes inward from the inner surface of the cylindrical portion 20c and has a T-shape in plan view. This latching | locking part 21 is distribute | arranged to the side away from the shielding wall 2a of the turning member 2 of the cylinder part 20c.

  Moreover, the holding | maintenance part 20 is provided with the bezel 36 with which the opening edge part opened by the passenger | crew side of the cylinder part 20c mentioned above was mounted | worn. The bezel 36 is surface-treated in a metallic style and is formed in a ring shape.

The case 16 is locked by entering the slit 25a of the locking protrusion 25 provided on the portion 22 and engaging with the locking protrusion 25, and the holding portion 20 holds the display portion 13, The display unit 13 is positioned in front of the pointer 11. At this time, the bezel 36 surrounds the edge part of the accommodating part 22 accommodated in the cylinder part 20c. In this way, the holding unit 20 covers the display unit 13 so as to cover the center of the indicator unit 10 a of the dial plate 10, that is, the rotation center of the pointer 11 so that the display unit 6 can always be viewed from the passenger side. Hold.

  According to the present embodiment, the turn-back member 2 that is disposed on the occupant side of the moving body of the dial plate 10 and covers the display unnecessary portion of the dial plate 10 holds the display unit 13 that displays information indicating the state of the moving body. Since the holding part 20 is provided, it is possible to prevent the positional deviation and backlash between the turning member 2 and the display part 13 and to prevent the display deviation from occurring when the occupant of the moving body visually recognizes it. can do. In addition, the display can have a stereoscopic effect. For this reason, visibility and decorativeness can be improved.

  Further, the display unit 13 includes a display member 14 having a display surface 14a on which information is displayed, and a connecting member 15 that connects the display member 14 and a printed circuit board disposed on the side away from the occupant of the dial 10. And a case 16 that accommodates the display body 14 and the connection member 15, and a cover 17 that is attached to the case 16 and provided with an exposure window 29 that exposes the display surface 14a of the display body 14. The cover 17 is provided with a protective wall 28 that protrudes toward the case 16 and protects the connection member 15 accommodated in the case 16 when the cover 17 is attached to the case 16.

  For this reason, by attaching the cover 17 to the case 16, it is possible to protect the connection member 15 that connects the display body 14 accommodated in the case 16 and the printed circuit board. Connection reliability can be improved. Therefore, power can be reliably supplied from the printed circuit board to the display body 14, and information indicating the state of the moving body can be reliably displayed on the display body 14.

  Further, since the turn-back member 2 has a locking portion 21 that locks with the case 16 of the display portion 13 when the display portion 13 is held by the holding portion 20, the turn-back member 2 is securely attached to the turn-back member 2. It is possible to prevent the shift member 2 and the display unit 13 from being displaced or backlashed. For this reason, when the passenger | crew of a moving body visually recognizes, display shift can be prevented.

  Further, the display unit 13 is arranged in the case 16 and on which the light source 33 that illuminates the display body 14 is mounted, and the light guide plate 19 that guides the light from the light source 33 to the display body 14. And the case 16 has a substrate housing portion 24 for housing the display body substrate 18 in a state orthogonal to the display body 14, and the light source 33 is exposed to the substrate housing portion 24. A wall portion 24b that covers the surface 18a of the substrate 18 on which the light source 33 is mounted is provided.

  For this reason, since it can suppress that dust, dust, etc. adhere to the surface 18a in which the light source 33 of the display body substrate 18 is mounted, the display body 14 can be reliably illuminated by the light source 33. Therefore, information indicating the state of the moving body can be reliably displayed on the display body 14.

  Furthermore, since the cover 17 has the substrate pressing rib 30 that presses the display substrate 18 toward the case 16 when the cover 17 is attached to the case 16, the display substrate 18 is accommodated in the case 16. Can prevent rattling. Therefore, the display substrate 18 can be fixed in the case 16 with a simple structure.

  In the above-described embodiment, the speedometer 6a has been mainly described. However, in the present invention, it is needless to say that the tachometer 6b has the same configuration.

  Further, the above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments. That is, various modifications can be made without departing from the scope of the present invention.
