A spinning reel for fishing includes a rotor rotatably supported in a reel body, a drive mechanism for driving the rotor by operating a handle mounted on the reel body, a first reversal preventive mechanism for preventing the rotor from rotating in the direction of playing out a fishline by stopping the drive mechanism from rotating in the reverse direction at the time of casting the fishline, and a second reversal preventive mechanism for holding the rotor in a predetermined position by stopping the drive mechanism from rotating in the reverse direction. The first reversal preventive mechanism is formed of a rolling one-way clutch, and the second reversal preventive mechanism is caused to hold the rotor in the predetermined position by switching the first reversal preventive mechanism to non-working condition.
