A meter device includes an instrument panel, a coaxial motor, a central light source, a peripheral light source, and units. The coaxial motor includes rotation shafts which rotate around a single axis perpendicular to the instrument panel. The central light source is disposed near the rotation shafts. The peripheral light source is disposed more distantly from the rotation shafts than the central light source. The units rotate together with the rotation shafts, respectively. The units includes indicator parts, respectively. Each of the indicator parts guides light to emit the light, thereby indicating a surface of the instrument panel. The units include a first unit and a second unit. The first unit includes a light path which guides light from the central light source to the indicator part. The second unit includes a light path which guides light from the peripheral light source to the indicator part, and a non-light guide part that prevents the light of the central light source from being guided to the indicator part.

A light guide pointer and a light emitting pointer device which can reduce luminance unevenness at a light emitting face are provided. A lower face of a main pointer portion includes a separating face extending away from a light emitting face, thus light reflected by a front inclined portion of a light control space, that is not likely to travel in a direction away from the light emitting face, is not likely to reach to a corner which is a boundary between the separating face and a recessed portion. Consequently, light is not likely to be reflected by the corner between the separating face and the recessed portion, thereby preventing luminance to be partially high at the light emitting face and thereby reducing luminance unevenness.

A torque wrench provided with illumination structure and indicated graduations includes a tubular body bored with an insert hole and an illumination hole. The tubular body is provided therein with a graduated ring having its outer circumferential wall provided with a graduation marked portion, with an interval kept between the graduation marked portion and the inner tube wall of the tubular body. A lens is disposed at a location corresponding to the insert hole, and a light-emitting element is installed at a location corresponding to the illumination hole. Thus, light emitted by the light-emitting element will first illuminate the graduation marked portion and thereafter the reflected light of the graduation marked portion will pass through the insert hole and pass out the lens, enabling a user to clearly read the graduation marked portion.

A lighting and color scheme for instruments to allow an apparent color change of indicia and background between daylight viewing and night-time viewing when an instrument light is turned on. White indicia on a red background is conspicuous in daytime, but can be transformed to green indicia on black background when the instrument is illuminated with a green LED for night-time viewing.
