For example, a cross-coil type instrument used as a speedometer for an automobile has a structure as shown in FIG. That is, 1 is a pointer, 2 is a pointer shaft with pointer 1 fixed at the tip, and 3 and 3' are made of synthetic resin and are molded to be able to be divided into upper and lower parts and also serve as coil bobbins for storing a movable magnet 4, which will be described later. The upper housing and the lower housing 4 are fixed to the pointer shaft 2 and are rotatably supported in the housings 3, 3' via the pointer shaft 2. Two-pole magnetized movable magnets 5, 6, 7 is a cross coil wound around the outer periphery of the upper housing 3 and lower housing 3'; 8 is a case made of a soft magnetic material that also functions as a magnetic shield and a magnetic circuit formation;
9 is a dial plate for reading the rotation angle of pointer 1, 1
0 indicates a damping agent such as silicone filled between the lower end of the pointer shaft 2 and the lower housing 3', and 11 indicates a ball receiving the end of the pointer shaft 2. 12 is a printed circuit board supporting the above-mentioned crossed coil type instrument;

シスを大きくするといつた問題点があつた。 In the case of a cross-coil type instrument having such a structure, when assembling the instrument, especially when inserting the pointer 1 into the tip 2' of the pointer shaft 2, the pushing force P is applied from the outside of the pointer 1. The press-fit load is directly received at the lower end of the pointer shaft, and this may cause the pointer bearing part of the lower housing to deform, or the lower end of the pointer shaft may be crushed and deformed, resulting in indication hysteresis. When I made it larger, I encountered the same problem.

The present invention prevents deformation of the pointer shaft and pointer bearing part during assembly of such a crossed coil meter,
In order to obtain a crossed coil type instrument with high indication accuracy and reliability, especially when inserting the pointer into the pointer shaft,
It is an object of the present invention to provide a crossed coil type meter that can prevent the press-fitting load from acting on the lower end of the pointer shaft.

である。 That is, in the embodiment, the cross-coil type meter is provided on the bottom surface of the case 8, the lower housing 3', and the printed circuit board 12 from the outside of the cross-coil type meter to the inside of the cross-coil type meter. The through hole 14 penetrates to the movable magnet 4 in the diametrical direction 2 of the movable magnet 4.
The holes are bored in such a way as to avoid the crossed coils 5, 6, and 7. Reference numeral 15 denotes a jig used when assembling the above-mentioned crossed coil type instrument, especially when press-fitting the pointer 1 into the pointer shaft 2. Two pillars 16 are erected to be inserted into the shaft.

立てることができる効果がある。 The above is the configuration of this embodiment.Next, its operation will be described.In the process of assembling the crossed coil type instrument having the above configuration, the pointer shaft 2 is finally
When press-fitting the pointer 1 to the tip 2' of the pointer 1, the crossed coil type instrument assembly before the pointer 1 is fitted is positioned on the jig 15, and the support 16 that is erected on the jig 15 is It is inserted into the through hole 14 of the crossed coil type meter and placed on the jig 15 on the crossed coil type meter assembly. As a result, the lower surface of the movable magnet 4 is brought into contact with the tip (upper end) of the column 16, and the movable magnet 4 is received by the column 16. Therefore, even if the pointer 1 is pressed into the tip 2' of the pointer shaft 2 in this state,
Since this press-fitting load is received by the support column 16 of the jig via the movable magnet 4, the pressing load is not applied to the lower end of the pointer shaft and the bearing hole 17 of the lower housing 3'. Pointer receiving part of lower housing 3' (bearing hole 17)
In addition, problems such as when the lower end of the pointer shaft 2 is deformed by the press-fitting load of the pointer can be solved, and this has the effect of making it possible to assemble a crossed coil type instrument with excellent indicating performance and reliability.

Therefore, according to the crossed coil type instrument of the present invention, when assembling the instrument, it is possible to insert the support of the jig into the through hole 14 and to receive the lower surface of the movable magnet 4 at the tip of the support. Therefore, when the pointer is press-fitted onto the pointer shaft, the pressing load is not applied to the lower end of the pointer shaft and the bearing hole 17 of the lower housing 3', and therefore, the pointer bearing hole of the lower housing 3' is not affected. (Bearing hole 17)
Also, problems such as when the lower end of the pointer shaft 2 is deformed by the press-fitting load of the pointer can be solved, and this has the effect that a crossed coil type instrument with excellent indicating characteristics and reliability can be assembled.
