Spinning reel handle assembly

A spinning reel handle assembly to be detachably mounted to a spinning reel master gear shaft in which a non-circular through hole is formed, the spinning reel handle assembly comprising:

• a handle shaft unit having
• a head portion for interlocking with either end of the master gear shaft,
• a trunk portion extending from said head portion, such that said trunk portion is adapted to be non-rotatively inserted into the non-circular through-hole of the master gear shaft, and
• a first threaded portion formed on a tip of said trunk portion;
• a handle aim unit having
• a boss portion for interlocking with either end of the master gear shaft,
• a second threaded portion formed in said boss portion for engaging with said first threaded portion, and
• an arm part extending from said boss portion in a direction intersecting the master gear shaft;
• and
• a handle grip fitted on a tip of said handle arm unit, wherein
• said first threaded portion is female screw threads that open on the tip of said trunk portion, and
• said second threaded portion is a male screw that protrudes from said boss portion.
