Abstract
A master gear includes a shaft made of an aluminum alloy, a gear portion, and an annular member made of stainless steel alloy. The shaft is screwed onto a handle shaft, a gear portion that is integrally formed on the outer periphery of the shaft. The shaft is supported by the reel unit at rotational support portions via bearings and has female threaded portions on its ends such that the handle is screwed to one of the female threaded portions. The gear portion is arranged on an outer periphery of the shaft portion between the rotational support portions, and meshes with a pinion gear. The annular portion is mounted to the outer periphery of the shaft such that at least part of the annular member is disposed not between the rotational support portions. With this structure, it is easy to remove bearings from a master gear of a spinning reel.
