An indicator instrument for a vehicle includes a rotational indicator that indicates a vehicle state parameter, and a stepper motor that rotates the rotational indicator. The stepper motor includes an output gear, a reduction mechanism, a motor casing housing the output gear and the reduction mechanism. The output gear includes an output shaft rotatable together with the rotational indicator, and a last-stage gear extending radially outward from the output shaft. The reduction mechanism includes a reduction gear engaged with the last-stage gear. The rotational indicator includes a rotational shaft press-fitted to a specified portion of the output shaft in the motor casing. The specified portion is displaced from the last-stage gear in an axial direction of the output shaft.
