Fishing reel

A fishing reel including a reel body for accommodating components of a reel and a drive mechanism provided in said reel body for winding a fishline around a spool, wherein:

• a rotating shaft which is rotated by the rotation of said drive mechanism and a gear are fitted to each other in such a manner as to be prevented from rotating relative to each other;
• a hollow cylindrical portion extending from said gear in an axial direction of said rotating shaft is formed;
• and
• a bearing is interposed between said hollow cylindrical portion and said reel body so as to rotatably support said rotating shaft by said reel body.

A concentrically coupling structure, provided to a fishing reel, for coupling a rotary shaft to a hollow cylindrical gear, said structure comprising:

• a circular outer surface of the rotary shaft;
• a noncircular outer surface of the rotary shaft, contiguous to the circular outer portion;
• a circular inner surface of the gear, to be fitted to the circular outer surface;
• a non-circular inner surface of the gear, contiguous to the circular inner surface, and to be fitted and non-rotatably coupled to the noncircular outer surface;
• and
• a resilient member provided to at least one of an interface between the circular inner and outer surfaces and an interface between the noncircular inner and outer surfaces.
