Abstract
A panning head for a photographic tripod or the like has a base and a panning body rotatable about a pan axis. A pivot shaft on the base extends into a cavity in the panning body, and a transverse forked retaining wedge captures the shaft to keep the base and panning body together, and includes an exteriorly accessible screw setting for adjusting the degree of friction between the two and consequently the effort required to turn the panning body on the base.
