Jumping toy top

Abstract

A toy top that can repeatedly jump on a curved playing surface to attack an opponent toy top from above. The jumping toy top includes a toy main body, a spinning shaft body having a spinning shaft, and a shaft body supporting portion disposed on the toy main body to support the spinning shaft body. A distal end of the spinning shaft has one side projecting downward more than another diametrically opposite side to configure a portion to contact a playing surface of a playing board. When the jumping toy top spins on a central axis of the toy main body, the contact portion revolves around the central axis of the toy main body in a circular orbit.
