Zusammenfassung:	PURPOSE:To assemble an electric table lamp in the simple structure with a good assembling property. CONSTITUTION:One end of a coil spring member 58 for generating a rotational moment capable of canceling a rotational moment generated by a lighting tool 6 is locked at one end of an arm 4 for supporting the lighting tool 6 at the other end thereof. This locked point is positioned in such a direction as to form a predetermined angle with respect to an axis of the arm 4 and deviated by a preset quantity from the turning center located on the axis. The other end of the coil spring member 58 is fixed to a fixing member 8. Consequently, the rotational moment generated by spring force of the coil spring member 58 is balanced with the rotational moment generated by the lighting tool 6 even if the arm 4 for supporting the lighting tool 6 is turned within an arbitrary angular range.
