続構造。 A caulking sleeve is used, which is a cylindrical metal fitting sealed at one end, has a hole for nipple insertion in the center of the end wall on the sealed side, and is open at the other end for hose insertion. After inserting the hole from the tip of the nipple toward the base, caulk the sealing side end of the sleeve, and fix the sleeve by biting the periphery of the hole into the base of the nipple. Insert an elastically deformable hose toward the base, connect the nipple and hose by inserting the hose between the outer peripheral surface of the nipple and the inner peripheral surface of the sleeve, and then caulk the middle of the outer periphery of the sleeve to connect the hose. In the connection structure between the hose and the swage-type nipple that is fixed to the nipple,
A nipple and a hose, characterized in that at least a part of the periphery of the hole provided in the center of the sealing side end wall of the caulking sleeve is provided with a convex part or a concave part for hooking the sleeve to the base of the nipple. connection structure.
