Definitions

  • the present invention relates to a spinning top toy.
  • the spinning top toy described in Patent Document 1 it is designed to improve an offensive power or to keep a stable rotation by controlling a rotation balance automatically in response to a rotation speed.
  • a plurality of guide grooves which are inclined upward from the rotation center side toward the outer peripheral side and which are radially extended, are provided in the spinning top toy body.
  • a weight member such as a metal ball, etc. is movably arranged in the inside of each guide groove.
  • the metal balls are moved toward the outer peripheral side (peripheral edge part) along the guide grooves by the centrifugal force. Accordingly, the inertia moment of the spinning top toy becomes large, and therefore, it improves the offensive power (impact force) at the time of battle games. Further, at the time of slow speed rotation, the metal balls are moved toward the center side along the guide grooves. Accordingly, the inertia moment of the spinning top toy becomes small, and the rotation of the spinning top toy is stabilized.
