  In addition, a receiving surface 3D (inclined surface) is formed at the receiving port of the guide receiving portion 3A.

  In the second embodiment having the above-described configuration, in addition to the effects of the first embodiment described above, a guide receiving portion 3A provided with a receiving surface 3D (inclined surface) whose open side is divergent. Thus, there is a further effect that the positioning can be performed while guiding the mounting leg portion 11B provided on the holder 11 along the direction, and the assembly work can be performed smoothly. At this time, since the chamfer 11D is given to the outer peripheral corner portion on the lower end side of the mounting leg portion 11B, it is provided in the guide receiving portion 3A together with the receiving surface 3D formed at the receiving port of the guide receiving portion 3A. There is an effect that it can be guided and incorporated while being guided into the recessed portion 3B.

  FIG. 9 shows a third embodiment of the present invention, and FIG. 9 is a diagram showing an insertion state of the mounting leg portion 11B into the guide receiving portion 3A, which is the same as the first and second embodiments described above. The equivalent parts will be described with the same reference numerals.

  The third embodiment described here is different from the first and second embodiments described above in that the guide receiving portion 3A of the instrument case 3 and the lower end portion (tip portion) of the mounting leg portion 11B of the frame-shaped holder 11 are used. ) Is provided with a gap S.

  Therefore, by forming a gap S between the bottom of the recess 3B provided in the guide receiving portion 3A and the lower end (tip) of the mounting leg 11B, the components of the instrument case 3 and the holder 11 side Even if there is a variation in dimensions, the holder 11 and the printed circuit board 13 are held with reference to the tip (upper end) of the guide receiving portion 3A provided in the instrument case 3, so that the holder 11 is attached to the instrument case 3. In addition, the printed circuit board 13 can be firmly held, and thus an indicating instrument having excellent vibration resistance can be obtained.

  Further, by providing the gap portion S, even if there is a dimensional variation in parts between the instrument case 3 side and the holder 11 side, the printed circuit board 13 and the tip end portion (upper end portion) of the guide receiving portion 3A of the instrument case 3 As a result, the printed circuit board 13 and the holder 11 can be sequentially stacked and assembled with the instrument case 3 as a reference, thereby maintaining sufficient vertical assembly strength. In addition, the mounting legs 11B provided on the holder 11 can be assembled and held while being easily aligned along the recess 3B provided on the cylindrical guide receiving portion 3A. Assembling and holding can be performed while regulating the movement of the. Thereby, the fixing strength in the vertical and horizontal directions can be sufficiently maintained, and the tilt of the holder 11 that is cantilevered by the pair of mounting legs 11B can be prevented.

  In addition, this invention is not limited to the Example mentioned above, A various deformation | transformation implementation is possible in the range of the summary of this invention. For example, in the above-described embodiment, the shape of the mounting leg portion 11B provided on the holder 11 is formed by the mounting leg portion 11B made of a cylindrical protruding portion, and this shape (cylindrical protruding portion) is matched. The guide receiving portion 3A is formed so as to be provided with a concave portion 3B formed by a round hole. However, the shape of the mounting leg portion 11B is formed as a rectangular protruding portion, and a rectangular concave portion 3B is formed in accordance with this shape. Even if it does in this way, the same effect can be acquired.

  Further, as the chamfered portion 3D at the lower end side outer peripheral corner portion of the mounting leg portion 11B provided on the holder 11, the receiving surface 3D made of an inclined surface is provided in the second embodiment or the third embodiment. It can be changed as appropriate, such as an arc-shaped chamfered portion, and as a column-shaped mounting leg provided on the holder, a wedge-shaped mounting leg that is slightly tapered toward the tip side is formed. By forming the guide receiving portion on the instrument case side that receives the wedge-shaped mounting leg portion, it is easy to assemble, and it is possible to assemble without gaps after assembling.

  In each of the first to third 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 may be adopted. For example, a display device D1 such as an electroluminescent device or a fluorescent display tube may be provided in place of the display device comprising the liquid crystal display panel 10, and in addition to the display device D1, other display devices may be provided. -Notification means may be incorporated.

  In each embodiment, 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). By providing a slit portion that allows the pointer 8 to be bypassed (actuated) by bypassing the display D1, and configured to operate the pointer 8 through the slit portion, the pointer 8 has a “T” shape or a pointer. 8 may be set as a pointer 8 having a crank shape such that the distal end portion 8 is routed along the outer side, and as described in Patent Document 3 described above, the pointer is set horizontally. The indicator piece that extends in the direction and is positioned above the pivot fulcrum of the pointer and visually recognizes the tip side pointer indicating portion that is a part of the pointer from the outer peripheral portion of the indicator arranged on the front side of the pointer-type meter. The same applies to the holding 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 in which the indicator 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 cross-sectional view of an indicating instrument showing a third embodiment of the present invention.
