The same parts as those in the structure shown in FIG. 5 are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 4, in the lighting fixture, a socket mounting member 3 having a pair of lamp sockets 2 is attached to both ends of a fixture main body 1 having a substantially U-shaped cross section and the inside of the fixture main body 1 is attached. Attach the fixing member 4 to the bottom surface,
Between the lamp sockets 2 protruding from the socket window holes 7 at both ends of the reflecting shade 5 to the lower surface of the reflecting shade, the reflecting shade 5 is fitted to the lower face of the fixing member 4 and the screws 6 are screwed to the fixing member 4. A straight tube type fluorescent lamp 8 is connected to.

As shown in FIGS. 1 and 3, the instrument body 1 is formed in a substantially U-shaped cross section from a substrate 11 and rising portions 12 on both sides of the substrate 11, and the fixing member 4 is attached thereto. A slit-like fitting hole 13 is formed in the compatible longitudinal portion 12 corresponding to the position so as to face in the instrument longitudinal direction.

As shown in FIG. 2, the fixing member 4 has a mounting base portion.
21 and leg portions 22 fitted on both sides of the reflection shade 5 are formed in a substantially U shape, and a pair of locking pieces 14 to be attached to the instrument body 1 are cut and raised on the attachment base portion 21. ing. The locking piece 14 is formed in a fitting piece portion 23 that fits on the inner surface of the rising portion 12 of the instrument body 1 and a fitting hole 13 that is bent outward from the tip of the fitting piece portion 23. Locking piece 24 to be inserted
The interval between both fitting pieces 23 is configured to be slightly wider than the interval between the rising portions 12 of the instrument body 1, and the tip of the locking piece 24 is formed.
25 is formed in the shape of a curved surface having a distance R between the tips of the two locking pieces 24, and linear locking surface portions 26 are formed on both sides of the locking pieces 24. A screw hole 27 is formed in the mounting base portion 21 of the fixing member 4.

 Next, the operation of this embodiment will be described.

In order to attach the fixing member 4 to the instrument body 1, as shown in FIG. 3, the fixing member 4 is inclined with respect to the instrument body 1 and the pair of locking pieces 14 of the fixing member 4 is attached to the instrument body 1. Inserting between the ascending parts 12, one locking piece of the fixing member 4
The locking piece portion 24 of 14 is inserted into the fitting hole 13 of the one rising portion 12 of the device body 1, and the fixing member 4 is in a direction perpendicular to the device body 1, that is, the other locking piece of the fixing member 4. The device 14 is rotated in the direction in which it is fitted into the fitting hole 13 of the other rising portion 12 of the device body 1.
