ABSTRACT:
A pivotal mounting arrangement, which may be used for mounting a lamp on a vehicle body, comprises a plastics body having an integral boss provided with a hexagonal inwardly tapering recess therein. A socket element formed from a spring steel sheet has a cup-shaped central portion and six arms extending integrally upwardly therefrom. Outwardly projecting portions extend from the arm and the distance between opposed portions is greater than the corresponding dimension of the recess. A ball integral with one end of a screw-threaded rod is engaged in the socket element before the latter is forced fully into the recess. When disposed in position in the recess, the arms of the socket element are deformed inwardly and hold the ball captive while allowing same to rotate relative to the socket element.
This arrangement permits the boss to be formed out of a material which can be relatively rigid because the boss itself need not be resilient.
