STRUCTURE FOR GROUNDING IN HEAD DRUM DEVICE

摘要

PURPOSE: A structure for grounding in a head drum device is provided to improve productivity through easily assembling components and to improve service efficiency through easily disassembling the components. CONSTITUTION: A tip shaped ground member(56) fixed at an elastic member(54) of a fix member(52) is inserted to a through hole(53) of a boss(42A). A combining aperture of the fix member is combined to a fix shaft(2A) protruded from the boss. At identified state of combining/inserting apertures of boss/fix member, a fixing nut is inserted to combining aperture of the boss. At completed state of assembly, the ground member is elastically contacted to outer ring(55) of an upper bearing(6A) by the elastic member.
