The lighting fixture 9 here is a fixture in which a so-called round slim fluorescent lamp with a small bulb diameter can be mounted in double. For this reason, the curvature of the inner peripheral surface of the “C” -shaped fixing holder 93 corresponds to a round slim fluorescent lamp.
The cylindrical portion 52 is configured to be attachable to the fixed holder 93. That is, the outer diameter of the cylindrical portion 52 is configured to be substantially the same as the outer diameter of the bulb of the round slim fluorescent lamp. The length of the cylindrical portion 52 in the cylinder axis direction is longer than that of the fixed holder 93. Thereby, the cylindrical portion 52 can be attached to the fixed holder 93.

The appliance side fixing portion 50 has a flange portion 53 having a diameter larger than that of the cylindrical portion 52. The flange portions 53 are provided at both ends of the cylindrical portion 52 in the cylinder axis direction and on the outer peripheral surface side. That is, the flange portion 53 is formed so as to project outward from the outer peripheral surface of the end portion of the cylindrical portion 52 in the radial direction. Note that the inner diameter of the cylindrical portion 52 is constant from one end to the other end in the cylinder axis direction.

The bulging portion 74 bulges at a radius corresponding to the curvature of the inner peripheral surface of the C-shaped pressing member 96. The entire shape of the bulging portion 74 has a semi-cylindrical shape. When the extended portion 73 is fitted to the G10q terminal 94, the bulging portion 74 and the base portion 72 are supported by the pressing member 96.
The bulging portion 74 and the base portion 72 have a recessed portion 74a extending from the front side to the back side. Thereby, weight reduction of the adapter 7 is achieved. When viewed from the front side, the recessed portion 74a has a square shape and is formed in four pieces. When the bulging portion 74 is viewed from the front side, as shown in FIG. 23 (b), it has a “rice” shape due to the four recessed portions 74a.
Note that the terminal attachment portion is constituted by an extended portion 73. The supported portion includes a base portion 72 and a bulging portion 74.

(2) Fixing tool insertion portion The fixing tool insertion portion 71 has a rod-like portion 75 extending from the instrument side mounting portion 70. The rod-like portion 75 has a columnar shape as a whole. The outer diameter of the rod-like portion 75 corresponds to the inner diameter of the cylindrical portion 52 of the fixture 5.
