PURPOSE: To easily hold a 40W lamp, by providing such a structure that the middle part of the lower edge of longer side of a fixing frame fitted from the inside of 40W lamp of 30W and 40W lamp having different circumferences is made rectangular to mount on the flanges of reflection plate of the appliance body and the middle part of the shorter side of fixing frame is provided with a folding.

CONSTITUTION: The longer side 44 is positioned to mount on the reflection flange (b) of an appliance body A at a part of the middle of the lower edge and forced to get into contact with the external face of a cylinder 2 fitted to the external periphery of a 30W lamp B. And the crossing of the shorter side 40 and the longer side 44, or the corner of fixing frame 20 is set almost near the external periphery of the lamp so as to lap with the tube diameter of the 40W lamp C. A folding line 37 is cut at the center of the shorter side 40 to fold the frame flat at the folding line. In this way, the frame can be formed to be square cylindrical while fitting the lamp although the fixing frame 20 is of a simple structure and the lamp can be securely held in a serial working motion.
