  Subsequently, a procedure for replacing the battery unit 3 of the emergency lighting device X according to the present embodiment will be described.

  The operator who performs the replacement work pulls the cover 5 downward against the spring force of the mounting spring 7. When the cover 5 is pulled downward, the mounting spring 7 moves downward in the insertion groove 13 while bending the pair of spring portions 70 toward each other, so that the connecting portion 71 contacts the temporary holding portion 15 (temporary holding). Stop at (position) (see FIG. 4). Then, the operator removes the connecting portion 71 of the pair of attachment springs 7 from the temporary holding portion 15 and removes the cover 5 and the battery unit 3 from the main body 1. Next, the operator releases the connection between the first connecting portion 53 and the second connecting portion 310 by bending the bending piece 530 with a finger, and removes the battery unit 3 from the cover 5. Then, after fixing the new battery unit 3 to the cover 5, the operator inserts the mounting spring 7 into the insertion groove 13 again, and pushes it up from below to house the battery unit 3 in the main body 1, and 5 is attached to the lower surface side of the main body 1.

  If the emergency lighting device X (and XX) according to the present embodiment is configured as described above, the attachment / detachment of the cover 5 to / from the main body 1 and the attachment / detachment of the battery unit 3 to / from the main body 1 can be performed simultaneously. Therefore, the emergency lighting device X (and XX) according to the present embodiment has a battery (battery unit 3) that is different from the case where the attachment and detachment of the cover 5 and the attachment and detachment of the battery unit 3 are performed separately. The replacement work can be facilitated.

  In the emergency lighting device X (and XX) according to the present embodiment, the cover 5 is preferably provided with one or more first coupling portions 53 on the rear surface (upper surface) facing the main body 1. It is preferable that the battery case 31 is provided with one or a plurality of second coupling portions 310 that are detachably coupled to the one or the plurality of first coupling portions 53.

  If the emergency lighting device X (and XX) according to the present embodiment is configured as described above, the battery case 31 can be easily attached to and detached from the cover 5 by combining the first coupling portion 53 and the second coupling portion 310. To be done.

  Here, the structure of the 1st coupling | bond part 53 and the 2nd coupling | bond part 310 is not limited to the structure shown in FIG.7 and FIG.8. For example, the second coupling part 310 may be a groove in which the tip of the bending piece 530 of the first coupling part 53 is caught. In the embedded emergency lighting device X, the first coupling portion 53 may be integrally provided on the holding metal fitting 51 provided on the cover 5 and holding the attachment spring 7.
