To provide a rotary type spherical body fitting toy as stereo puzzle by arranging a plurality of slide piece with a shape precisely the same to make any sliding piece movable to an arbitrary position.

Grooves 1a is carved in a spherical body 1 as core along three great circle zones orthogonal to each other and on angular body-shaped island parts arranged at eight points surrounded by the grooves 1a, a plate material 2 which is similar to the islands and slightly larger that the island parts is mounted to fit in phase. Both sides of the grooves 1a are covered with the periphery part of the plate material 2 to make slide grooves with a T-shaped cross section out of the grooves 1a. Sliding pieces 4 each with a T-shaped cross section at fitting part thereof are so arrange to be inserted into the slide grooves thereby producing a rotary type spherical body fitting toy.
