A spinning reel includes a reel body, a main shaft, a crank for driving the main shaft to rotate, a tubular worm, a rotor coupled to the tubular worm to rotate therewith, and a speed shift device. The speed shift device includes a shell body configured to rotate with the main shaft, larger-dimension and smaller-dimension output wheels each meshing with the tubular worm, first and second tubular members, and a shifting unit. The shifting unit is configured to transmit rotational force of the shell body to one of the larger-dimension and smaller-dimension output wheels through a corresponding one of the first and second tubular members for driving the tubular worm.
