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 bearing, a groove of a semicircular cross-section is formed in a shaft itself so as to hold balls between this groove and the ball receiving concave surface of an outer race provided around the groove.
