<p>Disclosed herein is a rotary unit mounted to a magnetic toy. The rotary unit includes a main body (51), a coupling shaft (55), an auxiliary-shaft support sleeve (58), and one or more rings (59, 60). The main body is shaped like a disc having a bilateral symmetrical structure, with a toothed rim (52) provided around the circumferential surface of the main body. The coupling shaft protrudes from the center of one side of the main body, with a coupling end (56) provided on an end of the coupling shaft. The auxiliary-shaft support sleeve (58) is provided at a position around a shaft hole bored in a center of the other side of the main body. The rings are symmetrically provided on both sides of the main body at regular intervals. This invention provides a structure allowing a user to comprehend an operational mechanism, in addition to increasing creative potential.</p> |
