  Next, with reference to FIGS. 6-7 (b), the attachment procedure of the attachment member 7 to the base member 9 is demonstrated. FIG. 6 is a perspective view showing the mounting member 7 and the base member 9. In FIG. 6, a part A of the first unit U1 shown in FIG. 2 is shown. In FIG. 6 to FIG. 7B, the third groove 59 is omitted for simplification of the drawings.

  As shown in FIG. 6, the mounting member 7 is mounted on the base member 9. The claw portion 25 is fitted in the second groove portion 47.

  In order to mount the mounting member 7 on the base member 9, the procedure shown in FIGS. 7 (a) and 7 (b) is followed. FIG. 7A is a plan view showing a state before the mounting member 7 is mounted. FIG. 7B is a plan view showing a state after the mounting member 7 is mounted. 7A and 7B, the first recess 41 and a part of the second groove 47 are shown by dot hatching for the sake of clarity.

  As shown in FIG. 7A, the worker causes the attachment member 7 to enter the first recess 41 by inclining the mounting member 7 with respect to the direction PD in plan view. The plan view shows that the mounting member 7 and the base member 9 are viewed from a direction orthogonal to the longitudinal direction and the short direction of the base member 9. Specifically, the engagement pieces 29b of the pair of engagement portions 23 enter the pair of second recesses 53, respectively. Then, the worker rotates the mounting member 7 in the rotation direction R (clockwise in FIG. 7A).

  The mounting member 7 is rotatable from a position where the engaging portion 23 enters the first recess 41 to a position where the engaging portion 23 engages with the first groove portion 43. Specifically, the positions at which the pair of engagement pieces 29b engage with the pair of first groove portions 43 from the positions at which the pair of engagement pieces 29b of the engagement portion 23 enter the pair of second recesses 53, respectively. Until then, the mounting member 7 is rotatable.

  Accordingly, as shown in FIGS. 7A and 7B, the mounting member 7 is substantially orthogonal to the direction PD from a position where the mounting member 7 is inclined with respect to the direction PD in plan view. When the worker rotates the mounting member 7 in the rotation direction R to the position, the pair of engaging portions 23 engage with the pair of first groove portions 43, respectively. Specifically, the pair of engagement pieces 29b engage with the pair of first groove portions 43, respectively. As a result, the mounting member 7 is mounted on the base member 9. The mounting member 7 may be mounted on the base member 9 by rotating the mounting member 7 in the direction opposite to the rotation direction R (counterclockwise in FIG. 7A).

  Here, in order to further facilitate the understanding of the mounting procedure of the mounting member 7, referring to FIG. 7A, the procedure before the engagement portion 23 of the mounting member 7 enters the first recess 41 (FIG. 7). The procedure before the procedure shown in FIG. The operator places the mounting member 7 at the mounting position of the mounting member 7 on the base member 9. In the present embodiment, the mounting position is near the end of the base member 9 in the longitudinal direction. Specifically, the worker places the mounting member 7 on the base member 9 so that the pair of engagement pieces 29b abut against the pair of edge portions 45 at the mounting position (hereinafter referred to as “mounting”). procedure"). Then, as described above, the worker causes the mounting member 7 to incline with respect to the direction PD and causes the engaging portion 23 to enter the first recess 41. The operator skips the placement procedure and moves the mounting member 7 from the position where the mounting member 7 is separated from the base member 9 while the mounting member 7 is inclined with respect to the direction PD in plan view. The engaging portion 23 may enter the first recess 41.

  As described above with reference to FIGS. 7A and 7B, according to the present embodiment, the engaging portion 23 of the mounting member 7 is caused to enter the first recess 41 of the base member 9. The mounting member 7 is mounted on the base member 9 by rotating the mounting member 7. Therefore, the mounting member 7 can be easily mounted on the base member 9 as compared with the case where the mounting member is inserted from the end of the base member and the mounting member is slid. For example, even when the base member 9 extends long along the direction PD, the mounting member 7 can be easily mounted on the base member 9.

  Next, the mounting member 7 mounted on the base member 9 will be described with reference to FIGS. 7B and 8. FIG. 8 is a cross-sectional view showing the luminaire 1 and includes a cross section of the first unit U1 taken along line VIII-VIII in FIG.

  As shown in FIGS. 7B and 8, a first direction D11, a second direction D12, and a third direction D13 are defined. The first direction D11, the second direction D12, and the third direction D13 are orthogonal to each other. The first direction D11 is parallel to the direction PD. The second direction D12 indicates the width direction of the base member 9 (for example, the short direction of the base member 9). The third direction D13 indicates a direction orthogonal to the base member 9 (for example, the contact surface 57 of the base member).

  As shown in FIGS. 7B and 8, the pair of engaging portions 23 of the mounting member 7 are engaged with the pair of first groove portions 43 of the base member 9, respectively. Therefore, the mounting member 7 can be mounted on the base member 9 without using a fastener such as a screw. As a result, the number of parts can be reduced as compared with the case where a fastener is used. By reducing the number of parts, the cost of the lighting fixture 1 can be reduced. Further, the mounting member 7 can be easily mounted on the base member 9 by engaging the engaging portion 23 and the first groove portion 43 without using a tool.

  Further, the first groove 43 of the base member 9 is recessed along the second direction D12. Then, the engaging portion 23 of the mounting member 7 engages with the first groove portion 43. Accordingly, the pair of first groove portions 43 restricts the movement of the mounting member 7 along the third direction D13. As a result, according to the present embodiment, the displacement of the mounting member 7 with respect to the specified position can be suppressed. The specified position of the mounting member 7 indicates, for example, a position immediately after the mounting member 7 is mounted on the base member 9.

  Further, the first groove portion 43 has a substantially tapered shape in cross section. Therefore, when the mounting member 7 is rotated in the rotation direction R and the engaging portion 23 (specifically, the engaging piece 29b) is engaged with the first groove portion 43 (FIG. 7A), the engaging portion 23 It becomes easy to guide (specifically, the engagement piece 29b) to the back of the first groove portion 43. As a result, according to the present embodiment, the mounting member 7 can be smoothly engaged with the first groove portion 43. Further, since the first groove portion 43 has a substantially tapered shape in cross-sectional view, the engagement portion 23 (specifically, the engagement piece 29b) has a narrow portion (specifically, the back of the first groove portion 43). It is pinched by the pointed part). Accordingly, the pair of first groove portions 43 further restricts the movement of the mounting member 7 along the third direction D13, and the movement of the mounting member 7 along the first direction D11 and the movement along the second direction D12. To regulate. As a result, according to the present embodiment, the displacement of the mounting member 7 with respect to the specified position can be further suppressed.

  Further, the pair of engaging portions 23 of the mounting member 7 are engaged with the pair of first groove portions 43 of the base member 9. On the other hand, the main body portion 21 of the mounting member 7 is in contact with the distal end portion 62 of the second groove portion 47 of the base member 9. The second groove 47 projects from the inside of the first recess 41 to the outside. That is, the tip 62 of the second groove 47 protrudes outside the first recess 41 with respect to the contact surface 57 (FIG. 4B). Accordingly, the main body portion 21 is pressed toward the fourth direction D14 by the distal end portion 62 of the second groove portion 47 while the pair of engaging portions 23 engage with the pair of first groove portions 43. As a result, the pair of engagement pieces 29b are urged toward the inner surfaces of the pair of first groove portions 43 in the fourth direction D14. When the engagement piece 29b is biased toward the inner surface of the first groove portion 43 in the fourth direction D14, the friction between the engagement piece 29b and the inner surface of the first groove portion 43 increases. As a result, according to the present embodiment, since the movement of the mounting member 7 along the first direction D11 is restricted, the displacement of the mounting member 7 with respect to the specified position can be further suppressed.

  The fourth direction D14 is parallel to the third direction D13 and indicates the direction in which the second groove portion 47 protrudes.

  Further, the pair of claw portions 25 of the mounting member 7 are fitted in the second groove portion 47 of the base member 9. Therefore, after the mounting member 7 is mounted on the base member 9, the mounting member 7 can be restricted from rotating in the rotation direction R (FIG. 7A) or in the direction opposite to the rotation direction R. As a result, according to the present embodiment, the displacement of the mounting member 7 with respect to the specified position can be further suppressed. Further, the claw portion 25 is fitted into the second groove portion 47 while being pressed against the pair of side wall portions 61 of the second groove portion 47. Accordingly, the movement of the mounting member 7 along the first direction D11 is further restricted. As a result, according to the present embodiment, the displacement of the mounting member 7 with respect to the specified position can be further suppressed. In addition, in order for the claw part 25 to press-contact with a pair of side wall part 61 favorably, it is preferable that the width dimension of the claw part 25 is slightly larger than the minimum gap | interval dimension of a pair of side wall part 61. FIG.

  In particular, the claw portion 25 is bent with respect to the main body portion 21 on the protruding side of the engaging portion 23. Therefore, after the claw portion 25 is fitted into the second groove portion 47, the rotation of the mounting member 7 in the rotation direction R or the direction opposite to the rotation direction R can be restricted. As a result, according to the present embodiment, the claw portion 25 can be prevented from coming off from the second groove portion 47.

  In addition, after fitting the nail | claw part 25 in the 2nd groove part 47 (refer FIG.7 (b)), a nail | claw part 25 is moved toward the inside of the 2nd groove part 47 using a tool (for example, flathead screwdriver). Further, the claw portion 25 can be inserted deeply into the second groove portion 47 by pressing. In this case, since the claw portion 25 is plastically deformed, the claw portion 25 maintains a state of being inserted deeply into the second groove portion 47. Therefore, it is possible to further restrict the mounting member 7 from rotating in the rotation direction R or the direction opposite to the rotation direction R. As a result, it is possible to further suppress the mounting member 7 from being detached from the base member 9.

  Further, the side wall portion 61 of the second groove portion 47 of the base member 9 is curved and has an inner curved surface and an outer curved surface. Therefore, when the mounting member 7 is rotated in the rotation direction R and the claw portion 25 is fitted into the second groove portion 47 (FIG. 7A), the claw portion 25 slides along the outer curved surface of the side wall portion 61. Move. As a result, according to the present embodiment, the claw portion 25 can be smoothly fitted into the second groove portion 47.

  Further, the main body 21 of the mounting member 7 is in contact with the pair of contact surfaces 57 of the base member 9. Therefore, according to the present embodiment, the mounting member 7 can be stably mounted on the base member 9.

  Further, a third groove 59 is formed in each of the contact surfaces 57 of the base member 9. Therefore, when the mounting member 7 is rotated in the rotation direction R and the mounting member 7 is mounted on the base member 9 (FIG. 7A), the mounting member 7 is compared with the case where the third groove portion 59 is not provided. Friction between the main body 21 and the contact surface 57 can be reduced. As a result, according to the present embodiment, the mounting member 7 can be smoothly mounted on the base member 9.

  Further, the pair of first holding portions 49 of the mounting member 7 holds the cover member 5. Therefore, according to this embodiment, since it is not required to provide a dedicated member for holding the cover member 5, the number of parts can be further reduced.

  Further, the pair of second holding portions 51 of the mounting member 7 holds the light emitting module 3. Therefore, according to this embodiment, since it is not required to provide a dedicated member for holding the light emitting module 3, the number of parts can be further reduced.

  The light emitting module 3 includes a substrate 71 and a plurality of light emitting elements 72. The plurality of light emitting elements 72 are mounted on the substrate 71. Then, both side portions of the substrate 71 are held by the pair of second holding portions 51. Each of the light emitting elements 72 is, for example, an LED. The plurality of light emitting elements 72 face the inner surface of the cover member 5 and emit light toward the inner surface of the cover member 5. As a result, the light is emitted to the outside of the lighting fixture 1 through the cover member 5. The light emitting module 3 may include a single light emitting element 72.

  As described above with reference to FIG. 8, the mounting member 7 is mounted on the base member 9, and the base member 9 holds the cover member 5 and the light emitting module 3. As a result, the first unit U1 is configured. Further, according to the present embodiment, the mounting member 7 and the claw portion 25 of the mounting member 7 and the first groove portion 43 and the second groove portion 47 of the base member 9 can be used without using a fastener. Can be fixed to the base member 9.

  Next, the first unit U1 attached to the second unit U2 will be described with reference to FIG. The pair of elastic portions 27 of the mounting member 7 of the first unit U1 fits inside the housing 12 of the second unit U2. Accordingly, the pair of elastic portions 27 are in contact with the pair of inner wall surfaces 75 of the housing 10, respectively. And since a pair of elastic part 27 has elasticity, the urging | biasing force acts toward the inner wall surface 75 from the elastic part 27. FIG. As a result, the first unit U1 is attached to the second unit U2. The pair of inner wall surfaces 75 face each other.
