Generally speaking, in the pointer return device of this main movable magnet type meter, the movable part of the meter, for example,
As known in Publication No. 43348 (specified in Figure 4), a part of the movable magnet etc. is cut out, or as known in Publication of Utility Model Application No. 56-86560, a weight or the like is added to the movable part. The method used is to make the weight unbalanced and use this unbalanced weight distribution to operate the movable part when the meter is not energized to return the pointer. In this case, since the weight of the movable part of the meter is unbalanced, there is a disadvantage that the indicated torque is affected by the mounting angle of the meter. Also, to avoid this, for example,
As is known from the above publication, a method has been adopted in which the movable part of the instrument is provided with a full return bevel, or a return magnet is disposed within the instrument body so as to face the movable magnet.

There is a disadvantage that the instrument body itself tends to be large, and when the above-mentioned structure in which the return magnet is assembled to the instrument mechanism, there is a problem that the assembly requires time and effort, which impedes productivity.

This invention solves the above-mentioned problems by winding a coil around a synthetic resin bobbin containing a movable magnet, and by protruding the upper end of a pointer shaft provided on the movable magnet from the bobbin and attaching the pointer to the tip. In a movable magnet type instrument in which the above-mentioned bobbin is housed in a substantially cylindrical case made of magnetic material to block external magnetism, an unused surplus space between the above-mentioned normal bobbin body and the above-mentioned cylindrical case is provided. A return magnet that exerts a magnetic effect on the movable magnet is arranged in an adjustable manner within the space, allowing the use of existing movable magnet instruments, and ensuring the return of the pointer with simple assembly work. In addition, by making the mounting position of the return magnet adjustable and movable within the space, it is possible to arbitrarily set the index characteristic according to the distance between the magnetic poles with the movable magnet. This allows for easy finger adjustment.
