For example, in the above-described embodiment, the anti-separation effect and the prevention of lateral vibration are obtained by forming the protrusions 11D and 11D1 provided on the holder 11 as protrusions having a T-shaped cross section or protrusions having a keyhole shape. However, the shape is not limited to the shape of the embodiment, and may be any shape that considers other retaining effects and prevention of lateral vibration, etc., and is accepted as a guide for assembly. The surfaces 3E and 3F are provided, but in addition to the receiving surfaces 3E and 3F, the lower end corner portion of the mounting leg portion 11B provided on the holder 11 side is chamfered, or the steadying portion provided on the holder 11 is provided. 11D and 11D1 by applying a chamfering portion having an inclined surface to the lower end surface portion or a wedge-shaped guiding portion that is slightly tapered toward the tip side. Each receiving surface 3E, it is those can also be expected a further effect of making it possible to perform the assembling work in alignment and smooth I 3F coupled with, it is also possible to combine with no gap yet after assembly.

  In the first and second embodiments, the display device D1 has been described using a display element made up of the liquid crystal display panel 10. However, any display device such as a display device made up of LED light emission can be adopted. For example, a display device D1 such as an electroluminescent device or a fluorescent display tube may be provided instead of the display device comprising the liquid crystal display panel 10, and in addition to the display device D1, An informing means may be incorporated.

  In the first and second embodiments, the second pointer portion 8B of the pointer 8 extends from the outside of the display 10 to the center side (the pointer 8 bypasses the display D1 in a “U” shape). Although an example has been shown, a slit portion through which the pointer 8 passes (activatable) bypassing the display D1 is provided, and the pointer 8 is configured to operate through the slit portion. It may be set as a pointer 8 having a letter shape or a crank shape in which the tip end portion of the pointer 8 is routed along the outside, and is described in Patent Document 3 described above. In addition, the pointer extends horizontally, is positioned above the pivot fulcrum of the pointer, and the tip side pointer indicator that is part of the pointer is visible from the outer periphery of the indicator placed on the front side of the pointer-type instrument. It is also possible to apply to the same type.

FIG. 1 is a front view of an indicating instrument showing a first embodiment of the present invention. FIG. 2 is a front view showing a state where the front cover is removed from the indicating instrument located at the center in FIG. FIG. 3 is an exploded perspective view of the main part showing an outline of the indicator and the pointer-type meter in FIG. 1. 4 is a cross-sectional view taken along line AA in FIG. FIG. 5 is an exploded cross-sectional view showing a state before assembly of the pointer-type meter and the display of FIG. FIG. 6 is an exploded perspective view of an indicating instrument showing a second embodiment of the present invention. FIG. 7 is a cross-sectional view of the main part showing the assembled state of the indicating instrument. FIG. 8 is an exploded perspective view of a main part showing an outline of the display and the pointer type instrument in FIG. 7. FIG. 9 is a front view showing a state in which the front cover is removed.
