Abstract:
A ball joint (1b) according to the present invention is provided with: a ball stud (10); a housing (11); and a ball sheet (sheet (12)). The sheet (12) is formed into a vertically-open cylindrical shape by an elastic body, and has a spherical space that houses a ball part (10b) in a cylindrical manner. The housing (11) has a spherical inner surface (11a) near the outer circumferential surface of the ball part (10b), and supports the ball stud (10) by housing the ball part (10b) in the inner surface (11a) with the sheet (12) therebetween.
