Japanese Patent JP5307083

B2

A ball joint includes a housing (11) with an opening (20), a ball stud (12) with a shaft portion (30) and a ball portion (31), a ball seat (13) accommodated in the housing (11) and including a recessed spherical surface (50) into which the ball portion (31) is inserted, a projecting portion (51) having an inner diameter smaller than an outer diameter of the ball portion (31) so as to inhibit the ball portion (31) from being dislodged from the recessed spherical surface (50), and a slope portion (52) formed at a hole portion (21) through which the shaft portion (30) is inserted, the slope portion (52) being shaped to have an inner diameter increasing from the projecting portion (51) toward the opening (20), and a caulking portion (80) including a projecting edge (25) formed at an end wall of the opening (20) in the housing (11) and folded toward an end surface of the ball seat (13), the projecting edge being arranged so as to overlap the end surface of the ball seat (13) and extending toward the projecting portion (51) and opposite the slope portion (52). The ball joint reliably prevents the ball seat (13) from being dislodged from the housing (11) and reliably positions the ball seat (13) vertically and radially with respect to the housing (11).
