Gyroscopic toy, characterized essentially by consisting of a rhombic frame of considerable mass, whose more separated vertices contain trunnions for a circular piece as a ring that surrounds and protects a central steering wheel, supported by its axle-tree, whose heads have entrants conical for their pivoting with respect to the conical ends of two pieces symmetrically located in axial arrangement in the trunnions corresponding to the nearest vertices of the rhombic frame, the steering wheel advantageously having a central recess and the pivoting parts spherical heads equipped with a diametral notch and a central cavity respectively.
