Abstract
A circuit board is attached in a displaceable manner to a lamp holder. When the lamp holder is attached to a holder housing, ends of pins extending from the holder housing are inserted into holes of the circuit board. At the time, the circuit board is guided and corrected for a positional shift by inclines at ends of the pins. Accordingly, a connector on an under surface of the circuit board is opposed to a connector on a circuit board in the holder housing side, whereby the two connectors can be properly connected.
