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.

An instrument device includes multiple projected scales projected toward a viewing position side in an axial line direction of a rotation center axis of an indicating needle and arranged at intervals in a circumferential direction, a display board including an insertion portion by which each of the projected scales is projected, an annular portion which covers an outer radial direction portion from the viewing position side in each projected end surface arranged on the viewing position side in each of the projected scales, and a lighting device for emitting light to the projected scales. The projected scale includes a scale visible surface in an inner radial direction than the annular portion in the projected end surface. The annular portion includes grooves provided to each of the projected scales.

A dial plate is in a disc shape. A pointer body is located at a center of the dial plate and rotational relative to the dial plate. The dial plate has a plurality of grooves extending radially outward from the center. The pointer body is configured to emit light radially outward to illuminate one of the grooves to produce a linear illumination extending linearly outward from the pointer body.

A metallic decorative part for a vehicle display device includes a substrate body molded with a synthetic resin, a metal thin film made of metal and provided on a surface of the substrate body, and a plurality of grooves formed on a surface of the metal thin film in accordance with a shape of the surface of the substrate body. The plurality of grooves are formed so that the radius of the curved surface of a corner forming an apex between adjacent grooves is larger than 0 and equal to or smaller than 38.0 μm. Accordingly, the metallic decorative part for a vehicle display device can appropriately ensure metal texture to be given to a viewer in a structure in which the metal thin film is provided on the surface of the substrate body made of a resin.

An adjustable information display apparatus for industrial, commercial, or domestic applications is described herein. The apparatus can include a band and a faceplate attached to the band. The band can be removably securable to an exterior surface of an object, such as an industrial gauge or pipe. The faceplate can be configured to receive one or more detachable components, such as one or more visual indicators or signage panels.
