ABSTRACT:
A turntable structure to control function selection for a media player. The turntable structure includes a base, a retaining ring, a bearing assembly, a rotating assembly and a rotating shaft. The base has a central post. The central post has a protrusion and a positioning portion formed thereon. The retaining ring is disposed on the central post and has an engaging hole and a positioning groove. The protrusion is engaged in the engaging hole and the positioning portion is engaged with the positioning groove. A gap exists between the retaining ring and the central post to prevent deformation of the central post resulting from thermal expansion and contraction. The bearing assembly encircles the retaining ring. The rotating assembly is assembled on the bearing assembly. The rotating shaft is fit in the central post and connected to the rotating assembly.
