As shown in FIG. 7, the lens portion 41 is disposed at a position facing the light emitting element 30 in a state where the cover member 40 is attached to the main body portion 2.
The lens portion 41 may be formed integrally with the upper surface portion 42 or may be configured by fitting a separate lens into a through hole formed in the upper surface portion 42.

また、カバー部材４０の側面部４３の外面側には、外側に突出した爪部４４が形成される。この爪部４４は、例えば車両内装部材に取り付けるために用いられる。
また、上述したように、カバー部材４０の側面部４３の内面側には、内側に突出した爪部４５が形成される。カバー部材４０を実装部２１の上方から下方に押し込むことにより、爪部４５が、実装部２１の爪係止部２３と嵌合することにより、カバー部材４０が実装部２１に固定される。 Further, a claw portion 44 protruding outward is formed on the outer surface side of the side surface portion 43 of the cover member 40. The claw portion 44 is used for attaching to a vehicle interior member, for example.
Further, as described above, the claw portion 45 protruding inward is formed on the inner surface side of the side surface portion 43 of the cover member 40. By pushing the cover member 40 downward from above the mounting part 21, the claw part 45 is fitted to the claw locking part 23 of the mounting part 21, whereby the cover member 40 is fixed to the mounting part 21.

なお、図３に示すように、カバー部材４０が本体部２に取り付けられた状態において、カバー部材４０の上面部４２と、収容部２２の上面部２２Ａとは略同一平面上にある。換言すれば、側面視において、カバー部材４０の上面部２２Ａと、収容部２２の上面部２２Ａとの高さは略一致している。   As shown in FIG. 3, when the cover member 40 is attached to the main body 2, the upper surface portion 42 of the cover member 40 and the upper surface portion 22 </ b> A of the housing portion 22 are substantially on the same plane. In other words, the height of the upper surface portion 22A of the cover member 40 and the upper surface portion 22A of the housing portion 22 are substantially the same in side view.

［発光装置１の効果］
以上説明した発光装置１によれば、実装部２１と収容部２２との接続部２６に傾斜面２７を形成したことにより、接続部２６に局所的に応力が集中することを抑制できるため、接続部２６の強度を向上できる。これにより、発光素子３０が取り付けられる導電性部材１１を保持する保持部材２０の強度を向上させることができる。 [Effect of light-emitting device 1]
According to the light emitting device 1 described above, since the inclined surface 27 is formed in the connecting portion 26 between the mounting portion 21 and the accommodating portion 22, it is possible to suppress the local concentration of stress on the connecting portion 26, and thus the connection The strength of the portion 26 can be improved. Thereby, the intensity | strength of the holding member 20 holding the electroconductive member 11 to which the light emitting element 30 is attached can be improved.

また、発光装置１では、実装部２１の上面である平坦部２１Ａは、収容部２２の上面部２２Ａよりも下方にある。
こうすることで、実装部２１の上面よりも収容部２２の上面が先に上方からの物体に当接するようになるため、発光素子３０が配される実装部２１の上面を保護できる。 Further, in the light emitting device 1, the flat portion 21 </ b> A that is the upper surface of the mounting portion 21 is below the upper surface portion 22 </ b> A of the housing portion 22.
By doing so, the upper surface of the housing portion 22 comes into contact with the object from above before the upper surface of the mounting portion 21, so that the upper surface of the mounting portion 21 on which the light emitting element 30 is arranged can be protected.

また、発光装置１では、カバー部材４０は、接続部２６の水平面２８と当接した状態で、実装部２１に取り付けられる。
こうすることで、カバー部材４０の取付位置を定めやすくなるため、カバー部材４０の取り付けが容易となる。これにより、カバー部材４０の取付時に、実装部２１に配される発光素子３０を損傷することを抑制できる。 In the light emitting device 1, the cover member 40 is attached to the mounting portion 21 in a state where the cover member 40 is in contact with the horizontal plane 28 of the connection portion 26.
By doing so, the attachment position of the cover member 40 can be easily determined, so that the cover member 40 can be easily attached. Thereby, at the time of attachment of the cover member 40, it can suppress that the light emitting element 30 distribute | arranged to the mounting part 21 is damaged.

また、発光装置１では、カバー部材４０は、接続部２６の水平面２８と、実装部２１の平坦部２１Ａに当接した状態で、実装部２１に取り付けられる。
こうすることで、カバー部材４０は複数点で支持されることとなるため、カバー部材４０のガタツキを抑制できる。
また、実装部２１の上面を平坦部２１Ａとしたことで、実装部２１の成形を容易とすることができる。 In the light emitting device 1, the cover member 40 is attached to the mounting portion 21 in a state where the cover member 40 is in contact with the horizontal surface 28 of the connection portion 26 and the flat portion 21 </ b> A of the mounting portion 21.
By carrying out like this, since the cover member 40 will be supported by multiple points, the rattling of the cover member 40 can be suppressed.
Further, since the upper surface of the mounting portion 21 is the flat portion 21A, the mounting portion 21 can be easily formed.

また、発光装置１では、カバー部材４０が実装部２１に取り付けられた状態で、収容部２２の上面部２２Ａと、カバー部材４０の上面部４２とは略同一平面上にある。
こうすることで、発光装置１の上面に大きな段差を設けないようできる。これにより、発光装置１の意匠性が向上する。 In the light emitting device 1, the upper surface portion 22 </ b> A of the housing portion 22 and the upper surface portion 42 of the cover member 40 are substantially on the same plane with the cover member 40 attached to the mounting portion 21.
By doing so, it is possible to prevent a large step from being provided on the upper surface of the light emitting device 1. Thereby, the designability of the light-emitting device 1 improves.

また、発光装置１では、カバー部材４０は、発光素子３０と対向するレンズ部４１を有する。
こうすることで、カバー部材４０とレンズ部４１を別体に構成する場合と比較して、発光装置１を小型化できる。 In the light emitting device 1, the cover member 40 includes a lens portion 41 that faces the light emitting element 30.
By carrying out like this, compared with the case where the cover member 40 and the lens part 41 are comprised separately, the light-emitting device 1 can be reduced in size.

また、発光装置１では、導電性部材１１の傾斜部１５は、接続部２６にインサートされ、傾斜部１５と、接続部２６の傾斜面２７の傾斜の向きは揃っている。
こうすることで、導電性部材１１の傾斜部１５を接続部２６により保護し、折れにくくすることができる。また、導電性部材１１の傾斜部１５が接続部２６にインサートされていることで、保持部材２０の接続部２６の強度を向上できる。 In the light emitting device 1, the inclined portion 15 of the conductive member 11 is inserted into the connection portion 26, and the inclination directions of the inclined portion 15 and the inclined surface 27 of the connection portion 26 are aligned.
By carrying out like this, the inclination part 15 of the electroconductive member 11 can be protected by the connection part 26, and it can make it hard to break. Further, since the inclined portion 15 of the conductive member 11 is inserted into the connection portion 26, the strength of the connection portion 26 of the holding member 20 can be improved.
