PROBLEM TO BE SOLVED: To provide a small bearing having a low profile, high spring rigidity, and a high shock absorbing rate. SOLUTION: This bearing is to hydraulically absorb a shock, and is connected to an ambient environment 14 so that an air chamber 11 circulates air through a valve 12 which can be opened and closed depending on the operating condition of a device to be supported, or a check valve 13. The bearing has a feature that, when the valve 12 is closed and the bearing is in an extending motion, the air flows into the air chamber 11 from the ambient environment 14 through the check valve 13, the air chamber 11 is expandable, and thereby, rigidity of the bearing is enhanced. |
