ABSTRACT:
A rotary structure adapted to be used as a spindle unit for a miniature motor or miniature rotor or as a tape guide roller for a VTR. In the structure of the rotary mechanism, instead of a conventional expensive radial ball bearings, a substantially V-shaped groove is formed in the shaft itself so as to hold balls between this groove and the tapered surface or concave spherical ball receiving surface of an outer race provided around the groove.
