PROBLEM TO BE SOLVED: To provide a ball joint capable of reducing abrasion in a resin sheet. SOLUTION: This ball joint includes: a ball stud 18 for arranging a spherical head part 23 having a spherical-like outside surface in its end part; a resin sheet for covering the outside surface of the spherical head part 23 and slidably holding the spherical head part 23; a lubricant filled between the spherical head part 23 and the resin sheet; and a housing for storing the spherical head part 23 and the resin sheet. A plurality of fine dimples 42 are formed on the whole outside surface area of the spherical head part 23. COPYRIGHT: (C)2009,JPO&INPIT
