The limited motion rotational joint employs two rotational members positioned as to be in frictional and rotatable engagement with each other around a common axis and in parallel spaced planes. The outer sections of the members are spaced apart, by the use of spacers, and a frictional foam is wrapped around the spacers while fitting between the outer sections. A compression unit is then used for circumferential application around the frictional foam to provide regulation of the frictional force applied to the rotational members.
