A tube joint comprises a joint body (16) having a through hole (12) to serve as a fluid passage provided along a direction of an axis B, a nut member for connecting a tube (20) to the joint body (16), and an insert bush (26) inserted and fitted to an opening (24) of the joint body (16) and having an insert section (36) to be inserted into the tube (20) and an expanded section (38) protruding from one end of the tube (20). The expanded section (38) is formed with first projections (46a to 46c) which make linear contact with an inner wall surface of the opening (24) and which function as seals. <IMAGE> |
