Claims

[Claims for Utility Model Registration] (1) A metal product comprising a cylindrical body with an open upper end and a flange, and a lower plate integrally fixed to the lower end of the cylindrical body, forming an air chamber inside. a base body, an air port attached to a side wall of the base body, a diaphragm portion made of an elastic body having a substantially disk shape and having a protrusion at the center of the upper surface that closes the air chamber of the base body; a protective cover that covers the outer circumference including the side surfaces of the protrusion; a screw receiver mounted on the center of the upper surface of the protrusion of the diaphragm; and a screw hole of the screw receiver exposed on the upper surface of the protrusion and the protective cover. An air spring type vibration isolator characterized by comprising: a metal upper plate arranged in such a manner that the vibration isolating device is (2) A diaphragm portion made of an elastic material that is approximately cylindrical and has outward flange portions formed at both ends and a buffer recessed portion in the cylindrical body portion, and each flange portion of this diaphragm portion is closely arranged. metal upper and lower plates that form an air chamber together with the diaphragm, and a cylindrical metal upper plate that is closely arranged on the lower surface of the flange on the upper plate side and on the outer peripheral surface of the flange above the buffer recess. The torso and
A cylindrical metal lower body part closely arranged on the upper surface of the flange part on the lower plate side and the outer peripheral surface of the flange part below the buffer recess, and attached to either the upper body part or the lower body part. An air spring type vibration isolator characterized in that it has an air port that sends air into an air chamber. (3) A diaphragm part made of an elastic body that is approximately cylindrical and has outward flange parts at both ends and a buffer recess in the cylindrical body part, and each flange part of this diaphragm part is closely arranged. metal upper and lower plates that form an air chamber together with the diaphragm, and a cylindrical metal upper body that is closely arranged on the lower surface of the flange on the upper plate side and on the outer peripheral surface of the flange above the buffer recess. a cylindrical metal lower body closely disposed on the upper surface of the flange on the lower plate side and on the outer peripheral surface of the flange below the buffer recess; 1. An air spring type vibration isolator comprising: a metal ring made of metal, and an air port that is attached to either the upper body part or the lower body part and sends air to the air chamber.
