Abstract
An automobile meter device of the type having a self-acting light-emitting needle or pointer is disclosed in which first and second current supply terminals connected with first and second electrodes of a light-emitting element are disposed on opposite side of a pointer boss. The current supply terminals include plug-in sockets extending parallel to a longitudinal axis of the pointer shaft. When the pointer boss is fitted over a meter shaft to assemble the pointer with a pointer drive unit, the sockets are automatically fitted over connector pins of fourth current supply terminals which are connected with a power source. With this construction, the meter can be assembled efficiently with utmost ease. The pointer boss may be electrically conductive and connected with one of the electrodes of the light-emitting element in which instance one of the current supply terminals may be omitted.
