載の弾性チユーブ。[Scope of Claim for Utility Model Registration] 1. An infusion pump that presses and seals at least two positions in a section of an elastic tube that communicates with a fluid supply source using a press drive means, and moves the press position to infuse infusion while press-sealing. The elastic tube is composed of a fluororesin tube and an elastic resin coated in a tube shape on the outer peripheral surface of the pressing position over a predetermined section in the center of the fluororesin tube, and the fluororesin and the elastic resin are made of fluororesin. An elastic tube characterized by having an integral structure in which an elastic resin is locked to a locking structure formed on the outer circumferential surface of the tube. 2. The locking structure in the elastic tube is a spiral convex portion integrally formed on the surface of the fluororesin tube, and the spiral convex portion has a wedge shape with an outer circumferential width larger than an inner circumferential width. The elastic tube according to claim 1. 3. The locking structure in the elastic tube is integrally provided on the surface of the fluororesin tube with a ring-shaped protrusion having a protrusion parallel to the cross section of the tube at a minute interval, and the width of the outer circumference of the ring-shaped protrusion is 2. The elastic tube according to claim 1, wherein the elastic tube has a wedge shape that is larger than the width of the inner peripheral portion. 4. The locking structure in the elastic tube is a convex body that integrally protrudes from the surface of the fluororesin tube every minute area, and the shape of the end of the convex part is larger than the shape of the attachment part. The elastic tube according to claim 1. 5. The elastic tube according to claim 1, wherein the locking structure in the elastic tube is provided with a carpet-like hair-like system integrally provided on the surface of the fluororesin tube.
