A spring support is accommodated in the socket housing so as to face the bottom of the base of the electric bulb, the spring support having an electric supply side electrode abutting against the electrode of the electric bulb. A coil spring is mounted in the socket housing so as to be located outside the spring support for urging the spring support so that it is raised toward the open end of the socket housing. The coil spring is disposed so as to be in parallel with the base of the electric bulb inserted into the socket housing. The length of the socket housing required for accommodating the coil spring can be reduced.
