ABSTRACT:
This invention relates to 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 substantially V-shaped groove is formed on a shaft itself so as to hold balls provided between this groove and the tapered surface or concave spherical ball receiving surface of an outer race provided around the groove.
