Claims

[Scope of utility model registration request]

A bobbin is formed by an upper frame and a lower frame made of synthetic resin, a plurality of legs are provided upwardly and downwardly protruding from the periphery of the bobbin, a movable magnet is built into the bobbin, and a movable magnet is inserted into the bobbin. The lower end of the inserted pointer shaft is pivotally supported by the lower frame, the upper end is made to protrude from the upper frame, the pointer is attached to the tip, and a terminal for electrical connection with the outside, such as a power supply terminal, is provided on the leg, and this terminal is connected to the lower end of the inserted pointer shaft. In a movable magnet type instrument in which a connected coil is wound crosswise around the bobbin so that the movable magnet is angularly moved by the combined magnetic field of the coil, and the bobbin is housed and fixed in an instrument case, the terminal is arranged. A movable magnet type meter, characterized in that at least one of the leg portions that is not connected is provided with a fixing portion for fixing a bobbin to the meter case.
