  • Patent number: 10442663
    Abstract: In a cage lighting device for an elevator, a lighting cover includes a main cover, a first auxiliary cover opposing a first cage wall, and a second auxiliary cover opposing a second cage wall. Respective dimensions of the first and second auxiliary covers in a lengthwise direction of the lighting cover are smaller than a dimension of the main cover in the lengthwise direction of the lighting cover. By loosening a first auxiliary cover fastening tool, the first auxiliary cover becomes capable of sliding in the lengthwise direction relative to a lighting cover attachment member between a position adjacent to the main cover and a position contacting the first cage wall.
