PIPE JOINT, SPACER PROVIDED IN PIPE JOINT, AND DIVIDING PIECE CONSTITUTING SPACER

WIPO Patent Application WO/2023/058574

A1

A spacer 40 for limiting insertion-direction movement of an insertion port 12 is mounted between the leading end 12a of the insertion port 12 and a back end surface 19 of a receiving port 15. The spacer 40 comprises: a tubular body 41 sandwiched between the leading end 12a of the insertion port 12 and the back end surface 19 of the receiving port 15; a contact section 50 contacting the back end surface 19 of the receiving port 15 at an end 41a of the body 41; an abutment surface 45 for centering that contacts the inner peripheral surface 20 of the receiving port 15; and a separation surface 47 that separates from the back end surface 19 of the receiving port 15 in the lead-out direction A of the insertion port 12. A gap 48 is formed surrounded by the separation surface 47 of the spacer 40, the back end surface 19 of the receiving port 15, and the inner peripheral surface 20 of the receiving port 15. The gap 48 is located further to the outer side in a radial direction B than the contact section 50 of the spacer 40. In the radial direction B, the separation surface 47 is formed between the contact section 50 and the abutment surface 45 for centering.
