と共に結合強度の増加を図ることができる。According to a first aspect of the present invention, there is provided a hose connector, wherein a nut screw for a cap nut and a hose insertion cylinder for inserting a hose are formed on the right side of the rotating head of the nipple and have a circumferential shape. A widening groove is formed in the groove. Then, when tightened with the cap nut, the hose and the sleeve are tightly inserted into the expansion groove, and at the same time, the spiral concave portion formed on the right inner surface of the cap nut engages with the right outer surface of the sleeve (rides up). And shrink the sleeve in the radial direction. At this time, if the cap nut is advanced while rotating, the sleeve tightens the hose, so that a frictional force is generated between the inner face of the sleeve and the outer face of the hose, and between the outer face of the sleeve and the inner face of the cap nut. However, when the spiral recess formed on the inner surface on the right side of the cap nut engages the sleeve, the contact area is small, so the frictional force is small, and since the spiral recess is thread-shaped, even after riding on the sleeve, When the cap nut is turned, the cap nut is also advanced, so that the cap nut can be easily tightened and the sleeve can be reduced in the inner diameter direction to prevent leakage. Further, in the hose connector according to the second aspect, since the circumferential projection is formed on the inner surface of the sleeve, the inner surface of the sleeve and the outer surface of the hose are more in close contact with each other, so that leakage can be more reliably prevented. The bonding strength can be increased.

きる。Then, the distal end portion 101a of the hose is inserted into the hose insertion tube 2. The projection 2a formed on the hose insertion tube 2 is a projection slightly larger than the inner diameter of the hose 101, so that it can be easily inserted. it can. Then, as shown in FIG. 2A, the distal end portion 101a of the hose and the distal end portion of the sleeve 5 are inserted into the expanding groove 3 and set. Next, the cap nut 10
When the inner screw 10a is screwed into the nut screw 1c of the nipple 1 and tightened, the pressing portion 10b formed on the inner surface of the cap nut 10 advances the pressed portion 5c formed on the sleeve 5 in the inner diameter direction (leftward). Direction), and furthermore, the flat cylindrical portion 5d of the sleeve 5 is pressed and reduced in the inner diameter direction by the parallel portion 10d formed at the center of the inner surface of the cap nut, so that the entire sleeve 5 is reduced in the inner diameter direction, It can be widely adhered to the outer surface of the hose 101 to prevent detachment and leakage.

In addition, since the spiral concave portion 10c has a screw shape, when the cap nut 10 is turned even after riding on the sleeve 5, the cap nut 10 also functions to advance, and the cap nut 10 can be easily tightened. At the same time, the sleeve 5 can be reduced in the radial direction to prevent leakage.
