A removable lead rubber bearing with a wedge is provided to improve damper function effectively because the maximum generation displacement of the bridge structure can be smoothly absorbed. A removable lead rubber bearing with a wedge comprises an upper support(1) which includes an elastic member, and a lower support(2) which is integrated in the upper support. The lower support comprises a wedge(4). The upper support comprises a primary elastic member placed between a cover plate(11) and a middle plate(13). The lower support comprises a secondary elastic body(22) arranged between a fastened plate(21) and a lower plate(23). The wedge(41) comprises an upper wedge part which protrudes toward the lower part of the middle plate of the upper support, and a lower wedge(42) which protrudes toward the upper side of the lower plate and contacts the upper wedge. |
