IT IS AN OBJECT OF THE PRESENT INVENTION TO PRODUCE A LIGHTWEIGHT SPINNING REEL MASTER GEAR ASSEMBLY TO BE ASSEMBLED IN A SHORT PERIOD OF TIME. A MASTER GEAR ASSEMBLY (9) IS ROTATABLY ATTACHABLE TO A REEL UNIT (2) OF A SPINNING REEL. THE MASTER GEAR ASSEMBLY (9) INCLUDES A MASTER GEAR SHAFT (10) AND A MASTER GEAR (11). THE MASTER GEAR SHAFT (10) IS ROTATABLY ATTACHABLE TO THE REEL UNIT (2) AND INCLUDES AN ATTACHMENT PORTION (LOE) HAVING A MALE THREADED PORTION (!OF) AT LEAST PARTIALLY ON THE OUTER PERIPHERAL SURFACE THEREOF. THE MATER GEAR (II) IS FIXED TO THE MASTER GEAR SHAFT (I 0) WHILE BEING INTEGRALLY ROTATABLE THEREWITH. THE MASTER GEAR (II) INCLUDES A FEMALE THREADED PORTION (LLA) SCREWED ONTO THE MALE THREADED PORTION (!OF) AND A CENTERED PORTION (LLB) WITH AN AXIS APPROPRIATELY ALIGNED BY THE ATTACHMENT PORTION.
