초록 ▼

A ball joint comprises a ball stud containing a ball at the leading end thereof, a socket incorporating therein a receptacle for admitting of the ball, and a resilient metallic ring containing a cut therein and adapted to retain the ball rotatably within the receptacle. The receptacle is formed of a main body and an auxiliary body adapted to be attached fast to the main body, and at least the main body is formed of a plastic material. Retention of the ball within the socket is accomplished by setting the resilient metallic ring in position within the receptacle before attachment of the auxiliary body to the main body, driving the ball into the receptacle thereby causing the equator of the ball to widen the cut in the resilient metallic ring and slide past the ring, and consequently enabling the ring to get hold of the ball.

대표청구항 ▼

A ball joint comprising: a ball stud having a ball at the leading end thereof; a plastic main body having a through hole which comprises a small-diameter portion on one side thereof, a large-diameter portion on the other side thereof and a tapered portion between said small-diameter portion and said large-diameter portion; a cup-shaped auxiliary body being snugly fitted in said large-diameter portion of said through hole in said main body and having the leading end thereof extending to said tapered portion of said through hole; means for detachably fixing said cup-shaped auxiliary body to said large-diameter portion of said through hole; a resilient metallic ring for retaining said ball within said through hole, said resilient metallic ring having a gap therein; whereby said ball stud, having said ball inserted into said through hole from said small-diameter portion and passed through said resilient metallic ring while enlarging the diameter of said resilient metallic ring, after inserting said resilient metallic ring into said through hole from said large-diameter portion and then fitting said cup-shaped auxiliary body snugly in said large-diameter, is prevented from being released from said through hole by said resilient metallic ring which has admitted insertion of said ball and contracted along said tapered portion of said through hole its diameter once enlarged.
