The hole 4 and the connecting hole 40 are movable. Further, a bushing 5 for positioning the power supply line 6 is attached to each power supply line insertion hole 4.
The bushing 5 is formed of an elastic material, and includes a substantially cylindrical tube portion 5a and a flange 5b formed to protrude outward over the entire upper end of the tube portion 5a. The cylindrical part 5a is formed to have a diameter larger than the diameter of the power line 6, and the movable range of the power line 6 is limited within the cylindrical part 5a by inserting the power line 6 into the cylindrical part 5a. The power line 6 is positioned. The bushing 5 is locked to the power supply line insertion hole 4 by pushing the cylindrical portion 5 a into the power supply line insertion hole 4 and the flange 5 b abutting on the periphery of the power supply insertion hole 4. Further, the bushing 5 is movable between the power line insertion holes 4 of the top plate part 20 and the chamfered part 22 via the connection hole 40. A connection terminal block 1 b to which one end of the power supply line 6 is connected is provided in the vicinity of the power supply line insertion hole 4 in the top plate portion inside the instrument body 2. The connection terminal block 1b is electrically connected to the socket 1 via a lead wire, and power is supplied to the socket 1 by connecting one end of the power line 6 to the connection terminal block 1b.
As shown in FIG. 1A, flanges 24 that protrude upward and downward are respectively formed in the left and right directions at the upper and lower edges of the opening of the instrument body 2. In addition, locking metal fittings 23 for locking the instrument main body 2 to the wall 3 are provided at substantially the center of the left and right side surfaces of the instrument main body 2. As shown in FIG. 3, the locking fitting 23 is formed so as to incline outward in the left-right direction from the rear side to the front side, and passes through slits (not shown) provided on the left and right side surfaces of the instrument body 2. It can be stored inside the instrument body 2. In addition, the locking fittings 23 are biased to the outside of the instrument main body 2, and when the instrument main body 2 is embedded in the wall 3, the inclined portions of the respective locking fittings 23 are arranged at the left and right ends of the opening hole 3 a. When pressed against the edges, the locking fitting 23 is pushed into the instrument body 2. When the locking fitting 23 is pushed into the space on the rear side of the wall 3, the locking fitting 23 pops out of the instrument body 2 by the urging force, and the front end portion of the locking fitting 23 comes into contact with the rear surface of the wall 3. The instrument body 2 is locked by sandwiching the wall 3 with the portion 24.

  Below the instrument body 2, as shown in FIG. 1 (a), it projects below the lower edge of the opening hole 3a in a state where it is connected to the lower side of the top plate 20 and the instrument body 2 is embedded. The protruding portion 21 is provided, and the socket 1 and the fluorescent lamp 1a are accommodated in the protruding portion 21. Further, as shown in FIG. 1A, a substantially rectangular reflecting plate 7 that is inclined downward toward the protruding portion 21 is provided at the lower edge of the opening of the instrument body 2 in the left-right direction. The light from the fluorescent lamp 1a is reflected by the reflecting plate 7 to irradiate the light to the outside through the opening hole 3a to obtain indirect light.

As shown in FIG. 1A, a frame portion 8 having a substantially rectangular opening portion 8b whose vertical and horizontal widths are narrower than the opening hole 3a is attached to the peripheral edge of the opening of the instrument body 2. The frame portion 8 is integrally formed with a reflection frame 8a that is inclined downward from the upper end edge of the opening portion 8b toward the rear side, and the fluorescent lamp 1a is attached to the instrument body 2 with the frame portion 8 attached thereto. The light from outside is reflected by the reflecting frame 8a in the same manner as the reflecting plate 7, so that the light is irradiated to the outside through the opening hole 3a. The frame portion 8 is attached to the appliance main body 2 by fitting attachment portions (not shown) provided on the left and right side surfaces to frame attachment brackets 9 provided on the left and right side surfaces of the appliance main body 2, respectively. (See FIG. 1 (a)).
Hereinafter, a procedure for embedding the lighting fixture of the present embodiment in the opening hole 3a of the wall 3 will be described. First, as shown in FIG. 4A, the protruding portion 21 is arranged in the space on the rear side of the wall 3 through the opening hole 3a, and the tip of the lower flange portion 24 of the instrument body 2 is brought into contact with the front surface of the wall 3. Let Next, the entire instrument body 2 is disposed in the space on the rear side of the wall 3 by rotating the instrument body 2 clockwise about the corresponding contact portion (see FIG. 4B).
By the way, when the power line 6 is routed inside the instrument body 2, the power line insertion hole 4 of the chamfer 22 passes through the vicinity of the wall 3 when the instrument body 2 is rotated as shown in FIG. In addition, when the power supply line 6 is inserted into the power supply line insertion hole 4, it is difficult to rotate the instrument body 2. Therefore, by rotating the instrument body 2 with the power line 6 inserted through the power line insertion hole 4 of the top plate 20, the instrument body 2 can be easily rotated without obstructing the power line 6. It can be embedded in the wall 3. After the instrument body 2 is embedded and disposed, for example, when the space on the rear side of the top plate portion 20 is narrowed by a heat insulating material or the like and the power supply line 6 is bent, as shown in FIG. Moreover, the power line 6 can be routed without being bent by moving the power line 6 to the power line insertion hole 4 of the chamfered portion 22 through the connection hole 40. At this time, since the bushing 5 can be moved together with the movement of the power supply line 6, the power supply line 6 can be moved and positioned without being damaged.
In addition, since the protruding portion 21 that protrudes downward is provided in the space on the rear side of the wall 3, the storage space of the instrument body 2 can be expanded without being limited by the depth in the space. Furthermore, since the fluorescent lamp 1a is housed in the protruding portion 21, it becomes difficult to directly recognize the fluorescent lamp 1a from the opening of the instrument body 2, and thus it becomes easy to obtain indirect light.

It is a figure which shows the lighting fixture of embodiment of this invention, (a) is sectional drawing seen from the right side, (b) is a partially expanded view of a chamfering part, (c) is a partially expanded view of a top-plate part.
