Abstract: An electrostatic sensor includes a fixed electrode, a movable electrode, an analyzing unit, a sliding member, and a crimping member. The fixed electrode is arranged along a predetermined direction. The movable electrode faces the fixed electrode. The analyzing unit is configured to detect a position of the movable electrode based on capacitance between the movable electrode and the fixed electrode. The sliding member is disposed between the fixed electrode and the movable electrode. The crimping member crimps the fixed electrode and the movable electrode together by a magnetic force.

Abstract: An illuminating device receives light emitted from a light source (22), and emits light. The illuminating device includes a tubular light guiding member (21) which receives the light emitted from the light source (22), and guides the light therein. The illuminating device further includes an annular luminous body (23) which is connected to one end portion of the light guiding member (21), and has a tapered surface (30) which is made to emit light by the light guided by the light guiding member (21). In this construction, the light entering the light guiding member (21) is guided spirally in the light guiding member (21), and is irregularly reflected by the tapered surface (30) so that the tapered surface (30) emits light.
