ABSTRACT:
A Yo-Yo formed of an axle and a pair of complimentary body segments, disposed in opposed relationship on the axle. Each body segment includes an inner and outer plastic shell having at their peripheries, concentric spaced annular rings which intermesh with each other. The inner shells have holes through which the axle projects. The outer shells each include a central hub with a metal sleeve which receives the end portion of the axle. The weight of the Yo-Yo is disposed essentially in the periphery of the segments by means of the intermeshing annular rings on the shells. A string encompasses an annular groove in the central portion of the axle. Adjacent the central groove, the abutting faces of the inner shells are provided with circumferentially disposed protuberances which snare the string. The opposed surfaces of each segment is parallel to each other, in their central positions and then diverge conically from each other and provide a curve angle relationship between the string and the faces of the body segments which will afford less likelihood of precession when the string engages the body segment.
