Claims

[Scope of utility model registration request]

A device unit equipped with a lamp is housed between a pair of light control covers provided with their opening surfaces aligned, and a distal end portion of a connecting shaft protrudes from one of the upper inner surface or lower inner surface of one light control cover. Correspondingly, a spring receiver is loosely inserted into the bottom wall of a connecting cylinder protruding from the inner surface of the other light control cover, and a spring receiver is attached to the tip of the connecting shaft within the connecting cylinder, and the spring receiver and the A coil spring is interposed between the inner surface of the bottom wall of the connecting tube and urges the light control covers toward each other, and a concave portion and a convex portion are fitted to the upper or lower inner surfaces of the light control covers. What is claimed is: 1. A lighting fixture characterized in that at least one side surface of the uneven portion is formed into a tapered surface.
