Abstract:
A toy top includes a shaft portion, a body, and a first attacking member and a second attacking member that are disposed at different circumferential direction positions of the body. The first attacking member is movable between an inner first position and an outer second position in a radial direction. The second attacking member is movable between an inner third position and an outer fourth position in the radial direction. The first attacking member is biased toward the first position and is movable to the second position by centrifugal force. The second attacking member is restrained at the third position when the first attacking member is at the first position and is released from restraint to be moved to the fourth position when the first attacking member is at the second position.
