Claims

[Scope of utility model registration request]

A magnet is housed in a bobbin case, coils are wound around the outer periphery of the bobbin case so as to cross each other, and the magnet is moved to follow the direction of a composite magnetic field generated according to the amount of current flowing through the coil. , a movable magnet type instrument in which a pointer shaft that operates in conjunction with the magnet is pivotally supported by the bobbin case, and a display plate is read by comparing the rotating display position of the pointer fixed to the pointer shaft; a collar having a hollow portion is fitted by penetrating the pointer shaft into the fitting portion, a stopper member is provided on the pointer shaft, and an engaging protrusion is provided on one of the hollow portion and the stopper member. providing an engagement groove in the other of the hollow portion and the stopper member that engages with the engagement protrusion and has a predetermined width from which the engagement protrusion is released within a rotation range of the pointer; The pointer is operated in conjunction with the rotation of the magnet in a state where the engagement protrusion and the engagement groove are engaged, and the pointer is operated in a state where the engagement protrusion and the engagement groove are disengaged. A movable magnet type instrument, characterized in that a holding member for stopping is fixed between the pointer shaft and the bobbin case.
