PROBLEM TO BE SOLVED: To provide a spinning reel for fishing capable of reliably obtaining concentricity of a spool shaft with respect to a pinion gear, and accurately reciprocating the spool shaft in a forward/backward direction without rattling when rotating a handle.SOLUTION: A spinning reel for fishing comprises a support member 60 which supports a front end side of a spool shaft 3a and has a concentric fitting part 60a for obtaining concentricity with respect to a pinion gear 8. The outer peripheral surface of the spool shaft 3a is not in contact with the inner peripheral surface of the pinion gear 8. The front end side of the spool shaft 3a is supported by the support member 60 on the front side from the front end of the pinion gear 8, and the rear end side of the spool shaft 3a is supported by a slide body 15 of an oscillation mechanism 12.
