A spinning reel includes, a spool, a spool shaft, a pinion gear, a tubular-shaped collar, a tubular-shaped nut, and an elastic member. The spool is configured to have a fishing line wound thereon when accompanied by rotation of a rotor. The pinion gear is disposed around the spool shaft and on which the rotor is non-rotatably mounted. The tubular-shaped collar is rotatably disposed on the spool shaft on an end side of the pinion gear in the axial direction of the pinion gear, and supports the spool shaft. The tubular-shaped nut is disposed to accommodate the collar and configured to screw onto the pinion gear. The elastic member is disposed between an outer peripheral surface of the collar and an inner peripheral surface of the nut.
