One object is to provide a fishing spinning reel which ensures the concentricity of the spool shaft (3a) with respect to the pinion gear (8) and enables the spool shaft to be smoothly and accurately reciprocated back and forth without rattling during rotational operation of the handle (5). The fishing spinning reel includes a support member (60, 9, 40, 45) supporting the front end of the spool shaft (3a) and having a concentric fitting portion (60a, 9a, 40a, 45a) for achieving concentricity with respect to the pinion gear (8). The spool shaft is supported at two points, one at the support member positioned in front of a front end (8e) of the pinion gear (8), and the other is a slide member (15) of an oscillation device (12), whereby an outer circumferential surface of the spool shaft does not contact the inner circumferential surface of the pinion gear and the gap (s) is maintained.
