Abstract:
PROBLEM TO BE SOLVED: To provide a low-cost instrument device that contributes to reduction of the number of components.SOLUTION: An instrument device 1 includes: a circuit board 14; a stepping motor 11, attached to the circuit board 14; and an indicator 10b, rotated by the stepping motor, the stepping motor 11 having a coil and a shield case 12b, covering a surface of the coil which is not opposed to the circuit board 14, and the coil having an exposed surface, facing the circuit board 14, and the circuit board 14 being provided with a ground part in a position facing the coil. The presence of the ground part eliminates the necessity of inclusion of a member sealing the surface of the coil of the stepping motor 11 which is opposed to the circuit board 14, in the stepping motor 11, and thus contributes to the reduction in the number of components of the stepping motor 11.SELECTED DRAWING: Figure 1
