Therefore, when the lighting device 10 is attached to the device attachment surface, the decorative frame 150 does not rattle.

  The holding members 155 are preferably arranged at positions that are equally spaced in the circumferential direction of the decorative frame 150. In the present embodiment, as shown in FIG. 3, three holding members 155 are arranged at substantially equal intervals in the circumferential direction of the decorative frame 150.

*** Other configurations ***
In the present embodiment, the three holding members 155 are arranged at substantially equal intervals in the circumferential direction of the decorative frame 150, but may be other than three. Specifically, there may be any number of positions such as two, four, five, seven, etc., at substantially equal intervals in the decorative frame 150. In addition, it is necessary to provide the instrument main body 140 with the rib 148 in the position which attaches the holding member 155 corresponding to the holding member 155. FIG. Further, the ribs 148 may not be inserted into the slits 554 for all the holding members 155, and there may be the holding members 155 that do not insert the ribs 148 into the slits 554.

  The holding member 155 may be disposed at a pair of opposing positions in the decorative frame 150. Also in this case, the number of holding members 155 is not limited to two, but may be any number such as four, six, and eight. Also in this case, the instrument main body 140 needs to be provided with a rib 148 at a position where the holding member 155 is attached corresponding to the holding member 155.

*** Explanation of effects of this embodiment ***
As described above, according to the present embodiment, since the holding member is downsized, the waste material can be reduced and the weight can be reduced.
Further, since the rib is inserted into the slit, the positioning of the holding member can be facilitated and the assemblability can be improved.
In addition, when attaching the holding member to the decorative frame, if the position where the holding member is attached is shifted, there is a risk that the screw cost for screwing may be reduced. However, since the holding member can be slid, the holding member is screwed. When doing so, the allowance for screwing can be increased, and assemblability can be improved.
