PROBLEM TO BE SOLVED: To simply fit a luminaire to a hook sealing body, by equipping a movable member, for supporting a luminair main body movable in an axis direction between inner and outer tubes, and providing a spring, for energizing the movable member to the hook sealing body side. SOLUTION: A holder 2 has an inner tube 17: tubular and to be externally inserted into an adaptor 15, and provided with an engaging part 8 for engaging with an engaged part 7, and an outer tube 18: to be connected to the inner tube 17, a movable member 19: for supporting an apparatus main body movable in an axis direction, between both the tubes 17 and 18, and moreover, a spring 20: for energizing the movable member 19 to a hook sealing body 4 side. When the holder 2 is assembled, it is inserted along a locking claw leading-in part 28 while a spring 20 is nipped, to rotate the movable member 19 by a degree same as the width of a falling-stop part 30, to insert a locking claw 27 into a locking part 29. When the locking claw 27 is entered into the locking claw leading-in part 28, a protruding portion strikes the falling-stop part 30 to prevent the falling of the locking claw 27. |
