Abstract
A knuckle or swivel joint of the half-ball and socket type comprising a stud terminating in an enlarged diameter half-ball member disposed in the socket member and having an end flat surface engaged by a resilient retainer cap disposed in the socket member. The retainer cap is elastically pre-loaded in an appropriate direction which causes firm engagement of the spherical bearing surfaces of the socket and ball in mutual swivelling engagement, thus, among others, compensating for wear.
