PROBLEM TO BE SOLVED: To provide a connection mechanism that can easily connect a light source section to a body section and that can suppress degradation of a connector in a lighting device in which the light source section and the body section are detachable.SOLUTION: A body section 100 of a lighting device includes a plate spring 130 that is a longitudinal plate spring and that includes a flat portion in a longitudinal direction and a circular arc-shaped circular arc-formed portion that is a convex portion from an end of the flat portion toward a light source section, the flat portion being fixed to the body section 100 near one longitudinal end portion of the body section 100; and a hook including an opening that is formed therein and on which a counterpart component is caught up, and arranged near the other longitudinal end portion of the body section 100. The light source section includes a connecting metal fitting having an opening formed therein to be penetrated by the circular arc-formed portion of the plate spring 130, an edge of the opening abutting on a neighboring circular arc-formed portion that is the circular arc-formed portion near the end of the flat portion in a state of displacing the neighboring circular arc-formed portion with respect to a no-load state; and a wire spring caught up on the hook and caught up on the opening of the hook in an elastically deformed state to press an edge of the hook. |
