ABSTRACT:
Disclosed herein is an insert-molded ball joint which is configured such that rotational frictional torque of a ball stud is kept below the appropriate level, pull-out strength of the ball stud is increased, and play of the ball stud is minimized. The ball stud has a spherical head. The spherical head of the ball stud is rotatably inserted into the ball seat. The housing covers the ball seat and a portion of the spherical head that is exposed from the ball seat. The upper end of the ball seat is disposed higher than the center of the spherical head. The housing includes a head support which covers the spherical head. A ball seat grease groove is formed in the inner surface of the ball seat. Housing grease grooves are formed in the head support in a vertical direction and meet the upper end of the ball seat.
