Abstract
A spacer for limiting the movement of a spigot in an insertion direction is mounted between a distal end portion of the spigot and a deep end face of a socket. The spacer has a cylindrical body sandwiched between the distal end portion of the spigot and the deep end face of the socket, a contact portion in contact with the deep end face of the socket on an end portion of the body, a centering contact face in contact with an inner surface of the socket, and a separating face that is separated from the deep end face of the socket in a removing direction of the spigot. A gap surrounded by the separating face of the spacer, the deep end face of the socket, and the inner surface of the socket is formed. The gap lies outside the contact portion of the spacer in a radial direction.
