20 is installed. As is clear from the figure, the air tube 20 is integrally attached to the inner end 13A of the mouthpiece 13 so as to communicate with the water supply pipe 40. Reference numeral 21 of the air tube 20 is a ring-shaped bulging portion. The reference numeral 14 indicates a tightening band 14.

Is made of stainless steel pipe or the like, and appropriate communication holes 17, 17 ... Are formed in the pipe. When forming the auxiliary chamber 15, the flexible tube 18 is formed as in the embodiment.
By interposing on the outer periphery of the communication partition portion 16 and squeezing both ends of the cylindrical main body 11, spaces at regular intervals can be easily formed.

Inflate 20 as indicated at 20A and 20B. Due to the expansion of the airbag 20, the air in the main chamber 12 flows into the auxiliary chamber 15 from the communication opening 17 of the communication partition section 16. The pressure rapidly increased in the pipe due to the expansion of the air tube 20 is absorbed, and the so-called water hammer impact is absorbed. When the pressure returns to the normal state, the airbag 20 also contracts to its original shape.
