A straight cold cathode fluorescent lamp is detachably held at the back of a dial plate by a plurality of fork-shaped holders to illuminate a plurality of scales formed on the front surface of the dial plate and accommodated in the reflector which is also detachably fixed to a casing of the indicator instrument. A circuit board is also detachably fixed to the reflector.

Indicating instrument for vehicle

An indicator for use in a vehicle instrument panel has a light conductive pointer illuminated by a light emitting diode or LED. In order to provide an increased illuminating surface of the pointer, a slit is formed on a cap to extend from the outer periphery of the cap to a portion above a center of rotation of the pointer driven by a driving shaft. A fixture is connected to the driving shaft and holds a light receiving portion of the pointer at the portion above the center of rotation and the LED in the optical alignment with the pointer at a portion off an axis of the center of rotation. A balancing weight is disposed at a portion opposite the LED with respect to the driving shaft in order to keep balance of the indicator.
