Pipe joint, spacer provided in pipe joint, and dividing piece constituting spacer

A pipe joint in which a spigot formed on a first pipe is inserted into a socket formed on a second pipe, the pipe joint comprising:

• a groove formed on an inner surface of the socket;
• a lock ring housed in the groove;
• an engaging portion that is formed on an outer surface of the spigot and is engageable with the lock ring from a deeper portion of the socket;
• a distal end portion formed on the spigot;
• a deep end face formed in the socket;
• and
• a spacer that is mounted between the distal end portion of the spigot and the deep end face of the socket and is for limiting movement of the spigot in an insertion direction,
• wherein the spacer includes:
• 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 at an end portion of the cylindrical body in a pipe axial direction;
• a centering contact face in contact with the inner surface of the socket;
• and
• a separating face that is separated from the deep end face of the socket in a removing direction along which the spigot is removed from the socket,
• wherein 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,
• wherein the gap lies outside the contact portion of the spacer in a radial direction, and
• wherein the separating face of the spacer faces the deep end face of the socket in the pipe axial direction and is formed between the contact portion and the centering contact face in the radial direction.
