Abstract
A ball joint includes a ball stud and a socket having a base portion that is annular about an axis extending in an insertion direction, multiple first protruding parts, and second protruding parts positioned between the first protruding parts. The second protruding parts rotatably hold the ball in cooperation with tips of the first protruding parts. The first protruding parts are each provided with an extension part that extends out sideways. An outer surface of the extension part is provided with an engagement part that engages with an edge part of the opening. The first protruding parts and the second protruding parts are each capable of deforming to bend in a radial direction with respect to the axis, and tips of the second protruding parts are positioned more in the insertion direction than edge parts of the extension part on a side of the insertion direction.
