PURPOSE:To miniaturize a package and facilitate the fitting/removing of a chassis to/from an arm by coupling a hook member rotatably fitted at the tip of the arm with the hole section of the chassis of a lighting fixture, and pressing the tip of the hook member to the inner periphery of the hole section. CONSTITUTION:Nearly the center of a moving claw 7 serving as a hook member is rotatably fitted at the tip of an arm 3 via a support shaft 6, and a hole section 4a couplable with a claw section at the tip of the moving claw 7 is formed on a chassis 4. The catch claw 10 of the chassis 4 is coupled with the pin 9 of the arm 3, the chassis 4 is rotated centering the pin 9 in the direction shown by an arrow B, and a claw section 7a at the tip of the moving claw 7 is inserted into the hole section 4a of the chassis 4. The moving claw 7 is rotated by a coil spring in the direction shown by an arrow A, the claw section 7a is brought into contact with the inner periphery of the hole section 4a, and the chassis 4 is hooked on the arm 3. The chassis 4 can be easily fitted to or removed from the arm 3, a lighting fixture main body 2 and the chassis 4 can be separately packed at the time of packing, and a package can be miniaturized. |
