Claims

[Claims for Utility Model Registration] (1) The hose 28 covers the elastic layer 32 that is expandable and contractible in the radial direction and the outer peripheral side of the elastic layer 32, and restrains the deformation of the elastic layer 32 outward in the radial direction. the elastic layer 32 has an exposed portion 38 exposed by peeling off the reinforcing layer 34;
The inner cylinder 56 has a through hole 58 that communicates between the inside and the outside, and is fitted into the inner circumferential side of the exposed portion 38, and the case body 68 is an annular shape that is sealed between the outer circumferential portion of the exposed portion 38 and the outer circumferential portion of the exposed portion 38. A pressure vibration absorbing device characterized by defining an air chamber 70 in a cross section. (2) The pressure oscillation according to claim 1, further comprising an air inlet 72 with a check valve that introduces air into the air chamber 70 and prevents backflow of intake air from the air chamber 70. Absorption device.
