2. Description of the Related Art FIG. 1 is a schematic view of a conventional air connection body used for a pneumatic massager or the like. In the figure, reference numeral 1 denotes an air connector, and the air connector 1
Comprises a receiving base 2 and an insertion base 3 inserted into the receiving base 2. The receiving base 2 is a receiving socket having a plurality of longitudinally extending through holes 4 and made of an elastic material such as rubber. A metal tube 5 is attached to the through hole 4 on one side of the receiving socket. The plug base 3 is a plug socket having a plurality of longitudinally extending through holes and made of a plastic material. A metal tube 6 is attached to a through hole on one side of the insertion base 3, and a plastic tube 7 is attached to a through hole on the other side. Thus, the insertion tube 6 attached to the through hole on one side of the insertion side socket is inserted into the through hole 4 on the other side of the receiving side socket.

[0003] Generally, in this kind of air connection,
When the insertion base 3 is inserted into the receiving base 2, it is required that the blown air, especially the compressed air, does not leak. In order to prevent the compressed air from leaking in the air connector having the above-described structure, the insertion tube 6 on one side of the insertion-side socket is connected to the through-hole 4 on the other side of the reception-side socket. Need to be fitted without any gaps.

[0004]

For this purpose, an insertion tube made of a hard material attached to a through hole on one side of the insertion side socket and a through hole on the other side of the receiving side socket are previously formed. It must be machined with the required dimensional accuracy. Further, it is difficult to perform the processing with dimensional accuracy as the number of through holes increases. Further, there is a disadvantage that processing cost and time are required to increase processing accuracy.

[0005] If the tube attached to the through hole on one side together with the insertion-side socket is manufactured by replacing a hard material such as metal with a soft material such as plastic, mass production becomes possible at low cost. However, when the tube is made by resin molding, there is a disadvantage that the resin shrinks in the mold at the time of molding and it is difficult to process the resin with a predetermined dimensional accuracy.

[0006] In the air connector used for the pneumatic massager, the frequency of insertion and removal of the receiving base and the insertion base constituting the air connector is high. Therefore, when the above-mentioned processing accuracy is enhanced, there is a drawback that when the insertion base is removed from the receiving base, even if oil is applied to the pipe body, the pipe is difficult to remove and difficult to use.

The present invention has been made by a ship in view of the above-mentioned conventional disadvantages.
