A fishing spinning reel includes: a spool (3) a rotor (2) for the winding of a fishing line around the spool by means of a line guiding portion an oscillation mechanism (10) having an oscillation gear (14) and adapted to convert the rotary motion of a handle (5) into back-and-forth reciprocating motion of the spool a switch mechanism (30) having an operation member (31) operable to switch between a restricting state for restricting the rotation of the spool and a free state for setting the spool free and a return mechanism (50) for returning the switch mechanism (30) in the spool free state to the restricting state by the winding operation of the handle. A return gear (51) for actuating the return mechanism (50) and the oscillation gear (14) are respectively meshed with a first gear (15A) and a second gear (15B) provided on a drive shaft. A meshing portion of the return gear (51) is disposed on a drive gear (7) side relative to a spool shaft (3a), while a meshing portion of the oscillation gear (14) is disposed on an opposite side to the drive gear (7) relative to the spool shaft (3a).
