Claims

[Scope of utility model registration request]

A pair of rail members fixed to both lower ends of a shelf board in a study desk with shelves, a horizontally long lighting fixture whose both ends are supported by the pair of rail members so as to be movable in a fixed stroke back and forth, and a lighting fixture. A long shaft body extending parallel to the longitudinal direction and rotatably supported by the lighting fixture, and approximately 90 degrees in the same direction from both ends of the shaft body.
A shaft member comprising a pair of bent arms extending along both end surfaces of the lighting device, and a pair of protruding ends projecting outward from the tips of both arms;
A lighting device for a study desk, wherein the pair of rail members have vertical grooves in opposing fixed positions into which protruding end portions at both ends of the shaft member fit vertically and slidably.
