Claims

[Claims for Utility Model Registration] (1) A pair of yo-yo bodies having recesses on their outer surfaces, a central shaft that supports the pair of yo-yo bodies at both ends with a predetermined gap in between, and a central shaft disposed in the recess. A pulley through which the central axis passes is clutched by a pair of brake members of a pair of clutch members provided and spring-biased in the direction of the central axis,
The clutch is configured such that the yo-yo body is prevented from spinning idly, and the clutch member rotates in the circumferential direction due to the centrifugal force generated by the rotation of the yo-yo body, thereby releasing the clutch of the pulley and causing the yo-yo body to rotate idly. A yo-yo toy comprising: a mechanism; and a string having one end fixed to the pulley and being wound around the pulley from the gap in the yo-yo body, the string being arranged opposite to the center of the inner surface of the pair of yo-yo bodies. An opening into which both ends of the pulley fit is provided, and a partition wall communicating with the opening and forming the center shaft hole for the center shaft is provided, and both end surfaces abut against the partition wall to position the gap. A yo-yo toy, characterized in that a pipe is inserted between the central shaft and the pulley. (2) The yo-yo toy according to claim (1), characterized in that the pressure contact portion of the pulley that comes into pressure contact with the braking portion of the clutch material is surrounded by a cylindrical body formed of an elastic, soft member with high frictional resistance. (3) A step is provided on the inner wall of the recess in which the spring-biased clutch material is stored, and the wall surface from the edge of the recess to the step is extended in the direction from the edge of the recess to the step. 2. The yo-yo toy according to claim 1, wherein the yo-yo toy is formed into an inverted tapered shape with a diameter gradually increasing, and a lid body covering the recess is press-fitted so as to be openable and closable. (4) A bolt is used as the center shaft, and a nut hole is formed in one of the yoyo bodies into which a nut to be screwed with the bolt is inserted, and the pair of yoyo bodies are removably fixed by the bolt and the nut. The yo-yo toy according to claims (1) and (2), characterized in that:
