FIG. 1A is a front view of the vehicle instrument, and FIG. 1B is a sectional view thereof. In FIG. 1A, 14 is a speedometer, 15 is a tachometer, a fuel gauge 22 and a water temperature gauge 24 are provided on both sides thereof, 19 is a dial, and 26 is a dial plate. As shown in FIG. 2B, the speedometer 14 and the tachometer 15 are mounted on the bottom plate of the case 20, and the fuel gauge 22 and the water temperature gauge 24 are mounted on the side surface of the case 20. A flexible printed circuit board 21 is provided on a lower surface or a side surface of the case 20, and a screw 25 that also serves as an electrode protruding from the instrument movements 14a, 15a, 22a, and 24a penetrates a hole provided in the case 20, and the flexible printed circuit board is provided. It is connected to the wiring 21.

The indicator shafts 14b and 15b projecting from the instrument movements 14a and 15a project from the dial 25 and are provided with pointers 14c and 15c at their tips. The fuel gauge 22 and the water temperature gauge 24 are mounted on the side surface of the case 20, and the pointer shaft 22b of the movement 22a of the fuel gauge 22 projects in the lateral direction unlike the speedometer 14 and the like. A pointer support portion 23 is provided at the tip of the pointer shaft 22b, and a pointer 23a is provided at the tip thereof. The water temperature gauge 24 has the same configuration. Gauges such as the fuel gauge 22 are mounted on the side surface of the case 20 as shown in FIG.
This is because, as shown in (b), the scale of the fuel gauge 22 is in the vertical direction, and the pointer is swung in the vertical swing direction. FIG.6 (b) is the figure seen from the side surface direction of the scale 22c.
Further, depending on the display design, as shown in FIG. 6C, the scale 22 in the horizontal-longitudinal direction for horizontally swinging the pointer 23a.
There is also c. Therefore, the gauge should be arranged in the speedometer 1
It is mounted at a position and direction different from those of the fourth grade.

[0004]

The vehicle instrument is usually installed at a predetermined angle in order to improve the visibility of vehicle information when it is mounted on the instrument panel. In the fuel gauge and water temperature gauge, the indicated value is indicated by vertical or horizontal deflection of the pointer. As shown in FIG.
A movement is incorporated in the side surface of the case 20, and a pointer shaft 22b thereof protrudes in the side surface direction. Therefore, guideline 2
When driving 3a, it is driven by an L-shaped member having a pointer 23a attached to the tip of the pointer support 23.
When the vehicle instrument is mounted on the instrument panel, as shown in FIGS. 7 (a) and 7 (b), the pointer axes of the speedometer 14 and the tachometer 15 have an angle at which the vehicle instrument is mounted, for example, It has an angle of 20 ° with respect to the horizontal direction, and the pointer axes of the fuel gauge 22 and the water temperature gauge 24 are horizontal because they are attached to the side surfaces of the case.

Referring to FIGS. 7A and 7B, the cross coil type indicating instrument will be described. In the cross coil type indicating instrument, the coil bobbin 30 of the indicating movement is used.
The indicator shaft 22b and the magnet rotor 29 are provided inside,
The coil 28 is wound around the coil bobbin 30, and the case 2
It is stored in 2c. Silicone oil 32 filling about half the space inside the coil bobbin 30 is injected. A pointer support portion 23 is provided on the pointer shaft 22b, and a pointer 23a is provided at the tip thereof. Vehicle instrument case 20
Is about 20 ° with respect to the horizontal as shown in FIG. 7 (b).
The pointer shaft 14b of the speedometer (tachometer) is set at about 20 ° with respect to the horizontal line. The fuel gauge (water temperature gauge) has a pointer shaft 2 as shown in FIG. 7 (a).
2b becomes horizontal. Therefore, in the fuel gauge 22 and the water temperature gauge 24, the silicone oil 32 may leak from the bearing portion of the pointer shaft 22b.

Further, in a vehicle instrument in which a plurality of indicating instruments are incorporated, that is, a so-called combination meter, as shown in FIG. 6, the display form of the scale must be a vertical type or a horizontal type, or various arrangement forms. I have to. In order to deal with such various arrangements, there is a drawback that the conventional method of directly driving with the pointer shaft cannot deal with it. Furthermore,
The flexible printed circuit board has to be extended to the side surface of the case of the vehicle instrument, resulting in an increase in cost as the size of the flexible printed circuit board increases. Further, there is a drawback that the arrangement of the flexible printed circuit board with respect to the case becomes complicated. For example, since the flexible printed circuit board is arranged according to the shape of the case, the flexible printed circuit board may have an abrupt bend, the reliability of the wiring at that part may be deteriorated, and the mounting process of the flexible printed circuit board becomes complicated. There are drawbacks. Further, in the conventional indicating instrument, an L-shaped one is used as a guide for the fuel gauge and the water temperature gauge, and there is a drawback that fixing the vehicle instrument to the case becomes extremely complicated, and it is relatively easy to install. It is possible and, moreover, an indicating instrument capable of eliminating leakage of silicone oil is desired.
