<p>When a slide portion (21) of a slider (20) slides on a slide surface (10a) formed on an upper surface of a base (10), the slider (20) is biased toward the base (10) by a stabilizer (30) comprising a small-diameter, bar-like member having elasticity. Specifically, the stabilizer (30) comprises a center portion (31), a link portion (32), a spring portion (33), and an abutting portion (34). When the abutting portion (34) abuts an abutting recess portion (40a) of a cover (40) attached from above the slider (20) and is biased toward the base (10), the spring portion (33) is elastically deformed about an arched portion (33a), creating a reactive force that causes a pressing portion (31a) comprising the center portion (31) to bias the slide portion (21) of the slider (20) toward the base (10). Thus, play can be eliminated with a small number of components.</p> |
