Abstract
A swivel bearing includes a base for connecting to a first member and a swivel gear for connecting to a second member to be turned relative to the first member. The base is provided on a top with a substantially ring-shaped receiving seat, into which the swivel gear is rotatably mounted. A threaded hole is provided on a predetermined position on the receiving seat for a screwing element to screw thereinto and set the receiving seat to a desired tightness relative to the swivel gear mounted therein. Thus, the second member may be turned to locate at a desired angular position relative to the first member.
