Pipe joint

A pipe joint, comprising:

• a spigot formed in a first pipe;
• a socket formed in a second pipe;
• a lock ring accommodation groove formed in an inner circumference of the socket;
• a lock ring accommodated in the lock ring accommodation groove;
• and
• a spigot engagement portion formed in an outer circumference of the spigot,
• the spigot engagement portion being caught on the lock ring from a deeper portion of the socket in a separation direction of the spigot in a state in which the spigot is inserted into the socket, thereby capable of preventing the spigot from being separated from the socket,
• wherein the socket has, on an inner circumference, an inner tapered surface expanding radially from a deeper end portion of the socket toward an opening end portion of the socket, and a bending angle limiting portion projecting inward from the inner circumference of the socket in a pipe radial direction,
• the inner tapered surface is formed between the lock ring accommodation groove and the deeper end portion of the socket, and
• the bending angle limiting portion prevents the first pipe from being bent with respect to the second pipe beyond an allowable angle.
