Abstract
A V-shaped leaf spring is provided, at one side of the leaf spring, with a plurality of pressing parts curved convexly toward the other side thereof and arc-shaped in cross section along a longitudinal direction of the leaf spring. The leaf spring is appropriately attached to a lighting apparatus main body so that a region of the leaf spring at a bent part thereof is located downward. Thus, upon installation of the lighting apparatus main body into an attachment hole provided in a ceiling, either one of the plurality of pressing parts abuts against the ceiling having different thicknesses from above, and a sufficient downward pressing force can be exerted on the ceiling having different thicknesses, thereby allowing the component to be fixed to the ceiling with a sufficient holding force.
