    • PROBLEM TO BE SOLVED: To provide a joining device having high versatility with which a plurality of members to be joined which are different in thickness can be joined. SOLUTION: This joining device 30 is provided with a die 1 which is divided into a plurality of die segments 2 in the peripheral direction around a wedge hole part 11 and a mandrel 20. Each segment 2 of the die 1 expands an objective part 41 expanding a pipe 40 by being moved outward in the radial direction of the pipe 40 with the mandrel 20. The die segments 2 are provided with a block part 3 having a first pressurizing projecting part 4 for pressurizing one portion 41b of two prescribed portions 41a, 41b of the pipe 40, the die segment main body 6 having a second pressurizing projecting part 7 for pressurizing the other portion 41b and a connecting means 15 for connecting the block part 3 and the die segment main body 6 separably.

    • PROBLEM TO BE SOLVED: To provide a tube-socket assembly which can maximize the binding force between a tube and a socket and which can minimize leakage from the connecting part between the tube and the socket, and to provide a method of manufacturing the same. SOLUTION: This tube-socket assembly includes a through-hole portion which is fastened to the tube on which first and second beads are formed and in which a through-hole portion is formed at a predetermined length, and a guide portion formed separated at a predetermined distance from the tube. In the assembly, a first taper portion having an inclined surface is formed on one side of the first bead, and the first taper portion forms a bead lock by being brought into line-contact with an inner end portion of the through-hole portion positioned in the socket.
