Abstract
A pipe joint in which a seal body and a spacer are mounted from the insides of pipes, wherein: a spigot of one pipe is inserted into a socket of the other pipe; and an annular accommodation space is formed between the inner circumference of the socket and the outer circumference of the spigot. Inside the accommodation space are accommodated: a seal body for sealing the gap between the socket and the spigot; a push ring that presses the seal body to keep the seal body in a compressed state; and a spacer that maintains the interval between the push ring and the deep end of the socket in the pipe axial direction.
