A tongue piece having a projecting part which is fitted in a hole part formed on the mounting surface of the socket, when the single-base type lamp is mounted to the socket, and which makes the engagement piece freely engaged with the engagement groove is provided on the surface where the mounting surface is mounted. In addition, the tongue piece, extended in the direction of a straight line which connects the rotation center of the surface where the mounting surface is mounted, to the base of the tongue piece, and the center of the projecting part in a planar view. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
