Abstract
A spherical joint of the present disclosure includes a ball member and a socket having an inner circumferential surface configured to spherically contact the ball member. The socket includes a cage part forming the inner circumferential surface and having an opening, and a bar-shaped connecting part provided to the cage part. A fastening member is disposed at the cage part so as to reduce a space of the opening in the extending direction of the connecting part and such that a gap is formed between the fastening member and the ball member. The opening is formed in a part of the inner circumferential surface other than a part where the largest load is applied.
