Installing device of push button

Abstract

Abstract PURPOSE: To carry out vertical movement of push button smoothly minimizing friction resistance between cylinder of push button and inner surface of installing hole, by hole, by providing vertical swellings inner surface of installing hole. CONSTITUTION: A gap between a cylindrical shaft 5 and the inner surface of installing hole 3 is formed, vertical swellings 9 are provided along the full length at long side on the inner surface of installing hole 3. Permitting to slide the outer surface of cylindrical shaft 5 by line-contacting the cylindrical shaft 5 with inner surface 2 of installing hole 3, minimizing rattle, the friction resistance between the cylindrical shaft 5 of push button 4 and the inner surface 2 of the installing hole 3 is minimized, the vertical movement of push button can be carried out smoothly.
