    • There is provided a spinning top excellent in the dimensional accuracy and excellent in the rotation balance and a method for manufacturing the spinning top.The spinning top 100 includes a rotating shaft 110 and a rotating outer circumference section 120 that is fitted to the outer circumference of the rotating shaft 110 so as to be coaxial with the rotating shaft 110, in which the rotating shaft 110 includes a parallel section 112 that has a circular cylindrical shape parallel to the rotation axis AX of the rotating shaft 110 and is fitted to the rotating outer circumference section 120, a tapered section 114 that continues to the parallel section 112, inclines by a predetermined angle with respect to the rotation axis AX of the rotating shaft 110, and is fitted to the rotating outer circumference section 120, and a tip section 116 that continues to the parallel section 112 or the tapered section 114. Generally perfect concentricity can be achieved by fitting the rotating shaft 110 and the rotating outer circumference section 120 to each other through a fitting surface including the parallel section 112 and the tapered section 114. Thus, a spinning top excellent in the dimensional accuracy and excellent in the rotation balance can be provided.
