  As shown in FIG. 9, the lighting fixture 1 further includes a building attachment member 7 and a wire 8. As shown in FIGS. 1 and 2, the building mounting member 7 has a plate-shaped portion mounted on the building, and the cover 4 is mounted at the opening 43 of the cover 4. The building attachment member 7 includes a top plate 71 that is a plate-like portion, a front leg piece 72, a pair of left and right leg pieces 73, and a pair of left and right fixing pieces 74. The building attachment member 7 is integrally formed of a metal plate such as a steel plate.

  As shown in FIG. 2, the top plate 71 is formed in a quadrilateral shape in which two opposing sides of the four sides are arcuate. A daruma hole 711 is formed at the front end of the top plate 71 so as to vertically penetrate therethrough. A hole 712 penetrating vertically is formed at the rear end of the top plate 71. The building attachment member 7 has a part of an electric wire opening 710 through which an electric wire connected to the terminal block 3 passes. An electric wire slit may be formed instead of the electric wire opening 710.

  As shown in FIG. 9, the wire 8 has a connecting portion 81 having a hole on one end side. A fastener 722 made of a screw is passed through the hole of the connection portion 81 from the rear side, and is screwed into a screw hole 721 formed in the leg piece 72 of the building attachment member 7. As a result, one end of the wire 8 is connected to the building mounting member 7.

  The wire 8 has a connecting portion 82 having a hole on the other end side. A fastener 416 composed of a screw is passed through the hole of the connection portion 82 from above, and the fastener 416 is screwed into a screw hole 415 (see FIG. 7) formed on the left side of the front wall of the bottom wall 41 of the cover 4. As a result, the other end of the wire 8 is connected to the cover 4. By providing the wire 8, the cover 4 is prevented from falling.

As shown in FIG. 2, the fixed piece 74 of the building mounting member 7 is formed with screw holes 741 penetrating left and right. In the pair of holes 421 formed in the left and right portions of the upper portion of the side wall 42 of the cover 4,
A fixing tool 742 made of a screw is passed from the outside, and the fixing tool 742 is screwed into the screw hole 741 to attach the cover 4 to the building mounting member 7.

  As shown in FIG. 3, the direction of the normal line 141 of the terminal block mounting surface 14 is inclined at an angle of 15 degrees or more and 75 degrees or less with respect to the direction along the axis 40 and toward the opening 43. As a result, as shown in FIG. 9, it is easy to insert the wire into the cover 4 through the opening 43 and insert the wire into the insertion holes 31 and 32.

  Further, the terminal block 3 is located at a position different from the electric wire opening 710 when viewed in the direction of the axis 40. This makes it difficult for dust such as dust to enter the opening 43 and adhere to the terminal block 3.

  As shown in FIG. 3, the terminal block mounting portion 13 is located on one end side (upper side in the present embodiment) in the direction of the axis 40 than the portion of the terminal block mounting member 11 mounted on the cover 4. Therefore, as shown in FIG. 2, when the electric wire is inserted into the insertion holes 31 and 32, the terminal block mounting member 11 may be bent. Therefore, as shown in FIG. 10, the terminal block mounting portion 13 is separated from the inner surface of the side wall 42 of the cover 4 with a gap 130 having a predetermined length or less. More specifically, the terminal block mounting portion 13 has a plate shape, and the left and right ends thereof are bent rearward to form the support piece 133. A gap 130 having a predetermined length or less is formed between the support piece 133 and the inner surface of the side wall 42 of the cover 4. In this case, when the electric wire is inserted into the insertion holes 31 and 32, even if the terminal block mounting member 11 bends, if the supporting piece 133 moves by a predetermined length, it comes into contact with the inner surface of the side wall 42 of the cover 4, As a result, the bending is suppressed. As a result, it is possible to suppress the terminal block mounting member 11 from being largely bent and plastically deformed. The predetermined length is preferably determined within a range in which the terminal block mounting member 11 is not plastically deformed, that is, in a range in which the terminal block mounting member 11 is elastically deformed. The terminal block mounting portion 13 may contact the inner surface of the side wall 42.

  As shown in FIG. 8, the connecting portion 82 on the other end side of the wire 8 is connected to the cover 4 at a position displaced from the center of gravity of the entire cover 4 to which the terminal block mounting member 11 is mounted. Further, the terminal block mounting portion 13 is located on the opposite side of the portion of the connecting portion 82 on the other end side of the wire 8 connected to the cover 4 with the center of gravity therebetween. Therefore, as shown in FIG. 11, when the cover 4 to which the terminal block mounting member 11 is mounted is suspended via the wire 8, the portion where the terminal block mounting portion 13 is located is lowered, and the insertion surface 33. Generally faces upward. The wire 8 contacts the edge of the opening 43 of the cover 4. This facilitates the wire 8 to be housed in the cover 4.

  Further, as shown in FIG. 4, the connecting portion 81 of the wire 8 on one end side attached to the building attaching member 7 intersects with the axis 40 direction. This makes it easier to insert the electric wire into the insertion holes 31 and 32.

  Further, as shown in FIG. 2, the front piece 67 of the second case body 65 has a flange portion 673. Further, as shown in FIG. 7, ribs 423 forming slits 422 are formed on the left and right sides of the inner surface of the side wall 42 of the cover 4, respectively. As shown in FIG. 8, the flange portion 673 enters the slit 422 between the ribs 423. As a result, the wire 8 is restricted from moving beyond the rib 423 and the flange portion 673 in the cover 4. The rib 423 and the flange portion 673 serve as the regulation portion 16 that regulates the movement of the wire 8 in the cover 4.
