Abstract

[PROBLEMS] To simply illuminate the darkness and objects, the commercial value of a flashlight has not deviated from the conventional range, and lacks preference.
A lens 4 is provided so as to be freely separable from a light source 2 and a projecting means 5 for displaying a pattern such as a character or a pattern. The projection means 5 includes an intermediate holder 5a that is screwed to the tip holder 11, a slide holder 5b that is slidably displaced on the outer periphery of the intermediate holder 5a, and a lens holder 5c that is screwed to the slide holder 5b. The pattern display body 5f is fixed in the intermediate holder 5a. The pattern display body 5f displays a projected pattern such as a pattern on a film-like translucent body. Since the slide holder 5b is slidably assembled to the intermediate holder 5a and holds the lens holder 5c in a fixed state, the lens holder 5c and the slide holder 5b slide together, and the light source 2 and the lens 4 The distance to can be changed arbitrarily.
