Abstract

A toy top includes a shaft portion, an additional part and an engaging part. The shaft portion includes a spinning shaft. The additional part is attached to the shaft portion movably in an axis direction of the spinning shaft. The engaging part engages the additional part with the shaft portion at different positions in the axis direction of the spinning shaft. An attachment position of the additional part is changeable by changing engagement of the additional part by the engaging part. A grounding state or a height of the shaft portion is changeable according to change of the attachment position of the additional part.

What is claimed is: 
     
         1 . A toy top, comprising:
 a shaft portion including a spinning shaft;   an additional part attached to the shaft portion movably in an axis direction of the spinning shaft; and   an engaging part which engages the additional part with the shaft portion at different positions in the axis direction of the spinning shaft,   wherein an attachment position of the additional part is changeable by changing engagement of the additional part by the engaging part, and   wherein a grounding state or a height of the shaft portion is changeable according to change of the attachment position of the additional part.   
     
     
         2 . The toy top according to  claim 1 , wherein the additional part is detachable from the shaft portion. 
     
     
         3 . The toy top according to  claim 1 ,
 wherein the additional part comprises a ring to which the spinning shaft can be inserted from an upper side so as to allow a bottom tip of the spinning shaft to protrude downward and which is disposed to circumferentially surround at least the bottom tip of the spinning shaft, and   wherein the ring changes a position of surrounding the spinning shaft according to change of the attachment position of the additional part so as to adjust a degree of protrusion of the bottom tip of the spinning shaft, and the ring is configured to be able to contact the ground depending on the degree of protrusion of the bottom tip of the spinning shaft.   
     
     
         4 . The toy top according to  claim 1 , wherein the additional part comprises a covering part which covers the bottom tip of the spinning shaft from a lower side to form a new spinning shaft, and the additional part is capable of changing a height of the shaft portion according to change of the attachment position of the additional part. 
     
     
         5 . The toy top according to  claim 1 , further comprising:
 a supporting part which is movable in the axis direction of the spinning shaft integrally with the additional part,   wherein the supporting part together with the additional part constitutes an adjusting member, and   wherein the engaging part includes:
 a recess disposed in one of the shaft portion and the adjusting member; and 
 a projection disposed in another of the shaft portion and the adjusting member and fittable in the recess. 
   
     
     
         6 . The toy top according to  claim 5 , wherein one of the recess and the projection is a plurality of recesses or projections that are arranged in a circumferential direction of the spinning shaft of the shaft portion at different positions in the axis direction, and the other of the recess and the projection is disposed in the adjusting member and selectively fittable in any of the plurality of recesses or projections. 
     
     
         7 . The toy top according to  claim 1 ,
 wherein the additional part is in any one of (i) a turnable state in which the additional part is turnable around the spinning shaft and (ii) an engaged state in which the additional part is engaged with any of the engaging part of the shaft portion, and   wherein the additional part includes a biasing member which biases the additional part to maintain the engaged state.
