Claims

[Scope of utility model registration request]

In a link ball joint connection structure in which a spherical seat is fixed to a link lever, a ball joint is fitted into the spherical seat, and a connecting rod is fixed to a fixed part of the ball joint, the ball joint protrudes in a direction opposite to the fixed part of the ball joint. Either one of the steady rest surface of the steady rest protrusion and the steady rest surface of the spherical seat that the surface of this steady rest protrusion comes into contact with is aligned with a line passing through the centers of the spherical part and the fixed part of the ball joint. A ball joint connection structure for a link, characterized in that the link is inclined so that both surfaces are brought into surface contact.
