ROLLER FOR SLIDE AND ROLLER ASSEMBLY FOR SLIDE

摘要

PURPOSE: A roller for a slide and a roller assembly for a slide are provided to include a bushing part which is arranged between a roller pipe and a central axis and is formed into a double bushing structure so that the roller pipe is rotatably combined, thereby spinning the roller pipe around the fixed central axis stably. CONSTITUTION: A roller for a slide comprises a roller pipe (20) in which a hollow is formed, a central axis (30) inserted in the both sides of the roller pipe and a bushing part (40) which is equipped between the roller pipe and the central axis and supports the roller pipe so that the roller pipe rotates around the central axis. The bushing part comprises an outside bushing (50) which is inserted in both sides of the roller pipe and bonded to the roller pipe and an inside bushing (60) which is equipped between the outside bushing and the central axis and slide-contacted with the outside bushing. A roller assembly for a slide includes the multiple rollers for a slide and a frame which is equipped in both sides of the central axis and includes a bracket in which the both end parts of the central axis are inserted and fixed.
