次に、補助反射板50を取り付ける動作について説明する。
まず、図4(A)に示すように、補助反射板50を枠体の下部開口48から上方へ挿入し、補助反射板50の下端部に設けられている引っ掛け部54を、枠体40の鍔部43の下面に当接させる。この状態では、図4(B)および図5(A)に示すように、補助反射板50の加締部55が、枠体40の補助反射板取付部47の内側から上方へ真っ直ぐに突出する。
Next, an operation for attaching the auxiliary reflecting plate 50 will be described.
First, as shown in FIG. 4A, the auxiliary reflector 50 is inserted upward from the lower opening 48 of the frame body, and the hook portion 54 provided at the lower end of the auxiliary reflector 50 is inserted into the frame body 40. It is brought into contact with the lower surface of the flange 43. In this state, as shown in FIGS. 4 (B) and 5 (A), the caulking portion 55 of the auxiliary reflecting plate 50 projects straight upward from the inside of the auxiliary reflecting plate mounting portion 47 of the frame body 40. .

次いで、補助反射板取付部47の上方へ突出している加締部55を、外側へ折り返して、枠体40の凸部471を内包するように折り曲げて加締める。このとき、枠体40のバネ取付部45における突出部451に対応する位置では、加締部55の先端を凸部471と台座473との間の溝474に押し込む。
その後、器具本体20からのネジ(図示省略)を枠体40の突出部452にねじ込んで、器具本体20と枠体40とを結合する。
Next, the caulking portion 55 projecting upward from the auxiliary reflector mounting portion 47 is folded outward so that the convex portion 471 of the frame body 40 is included and crimped. At this time, at the position corresponding to the protruding portion 451 in the spring mounting portion 45 of the frame body 40, the tip of the crimping portion 55 is pushed into the groove 474 between the convex portion 471 and the base 473.
Thereafter, a screw (not shown) from the instrument body 20 is screwed into the protruding portion 452 of the frame body 40 to couple the instrument body 20 and the frame body 40 together.

以上、説明した本発明にかかる実施形態の照明器具10では、LED31を含む器具本体20の開口部25の前方に取り付けられ、内面41に補助反射板50が取り付けられる枠体40に前面パネル35を載置する台座473を設けたので、前面パネル35は台座473に支持される。これにより、前面パネル109に傷や割れが生じにくいという効果が得られる。
また、台座473の内側に隙間472を設けたので、補助反射板50を加締めにより枠体40に取り付けたときに、加締部55の先端の角部55Aが前面パネル35に当接しないように取り付けることができる。これにより、前面パネル109に傷や割れが生じにくいという効果が得られる。

Since the mounting base 473 is provided, the front panel 35 is supported by the base 473. Thereby, the effect that the front panel 109 is hardly damaged or cracked can be obtained.
Further, since the gap 472 is provided inside the pedestal 473, when the auxiliary reflecting plate 50 is attached to the frame body 40 by caulking, the corner portion 55A at the tip of the caulking portion 55 does not contact the front panel 35. Can be attached to. Thereby, the effect that the front panel 109 is hardly damaged or cracked can be obtained.

また、台座473の内側に設けた隙間472に溝474を設けたので、加締めた補助反射板50の加締部55の先端部55Aを溝474に挿入することができる。これにより、加締めた先端部55Aが隙間472から外れるのを防止して、確実に補助反射板50を加締めることができる。   Further, since the groove 474 is provided in the gap 472 provided inside the pedestal 473, the distal end portion 55A of the crimped portion 55 of the crimped auxiliary reflector 50 can be inserted into the groove 474. Thereby, the crimped tip 55A can be prevented from coming off from the gap 472, and the auxiliary reflector 50 can be securely crimped.
