A joint device wherein a spherical shaft is pressed into and coupled with a spherical bearing member made of resin through an opening formed in a portion of a spherical bearing portion, a generally cylindrical skirt portion is formed at the opening of the spherical bearing member such that the minimum inside diameter thereof is smaller than the inside diameter of the opening, and a flex starting portion is formed at a position close to the skirt portion of the spherical bearing portion. The inner peripheral surface of the skirt portion is tapered off in a direction of becoming far off the spherical bearing portion. An inwardly raised portion is provided at a portion of the inner peripheral surface of the skirt portion. |
