Spinning reel

A spinning reel, comprising:

• a reel body;
• a rotor rotatable relative to the reel body;
• a spool shaft reciprocally movable relative to the reel body;
• and
• a drive body including a shaft, a first gear disposed on the shaft to rotate the rotor, and a second gear disposed on the shaft to cause the spool shaft to reciprocate with rotation of the rotor, wherein the shaft, the first gear, and the second gear are integrally formed by forging,
• the shaft having an axially extending central bore that extends from one end of the shaft to the opposite end of the shaft, the central bore having one section with reduced internal diameter over which the second gear is disposed, the reduction in internal diameter of the central bore in said one section causing said one section to have greater wall thickness than other sections of said central bore on axially opposite sides of said one section;
• the first gear including a first disk part disposed on an outer circumferential surface of the shaft, and a first tooth part protruding axially from the first disk part toward the second gear, and
• the second gear including a second disk part disposed on the outer circumferential surface of the shaft to be spaced apart from the first disk part, and a second tooth part protruding from the second disk part radially away from an axis of the shaft,
• wherein the second tooth part has a tip diameter smaller than an inner diameter of the first tooth part.
