Abstract
Provided is a coil instrument which can maintain a compact configuration even when a rotary shaft at a pointer side is subjected to a deceleration rotation by way of gears. The coil instrument includes a rotor shaft having a rotor magnet and a first gear, a pointer shaft having a second gear connected with the first gear, a housing which pivotally supports the pointer shaft and the rotor shaft in parallel, and a pair of coils which are arranged such that coils opposedly face an outer peripheral surface of the rotor magnet where the second gear is not arranged and give a rotational force to the rotor magnet upon energization thereof.
