Abstract: A pointer comprises an attached portion and a main body. The attached portion is attached to an instrument. The main body is fixed to the attached portion at a basic portion thereof and extending toward a free portion thereof. The main body has a reflective surface and a foil-stamping layer. The reflective surface is formed at an inclined surface of the basic portion and inclined to a traveling direction of light entering the main body. The foil-stamping layer is formed on a bottom surface of the main body and diffusely reflects light reflected by the reflective surface. The reflective surface is curved like a collective convex lens in a transverse direction of the inclined surface and a diffusive concave lens in a vertical direction of the inclined surface.

Abstract: A threaded fastener and a connector having the threaded fastener are provided, which threaded fastener includes: a shank, with a screw thread thereon, to be screwed to a mating member; and a head continuing from the shank and having a regular-polygonal cross section, wherein the head has an expanding portion with a cross-sectional area gradually becoming larger toward the shank and a reducing portion with a cross-sectional area gradually becoming smaller toward the shank, the reducing portion continues from the expanding portion in a direction of an axis of the shank, and the reducing portion is arranged nearer the shank than the expanding portion.
