The present invention relates to a bridge bearing having a movable stopper which prevents damage to a stopper or an elastic pad by moving the location of the stopper of the bridge bearing in response to the excessive slip of an elastic pad. The bridge bearing having a movable stopper of the present invention relates to a bridge bearing which is installed between a pier and a girder of a bridge, which comprises a lower plate which is to be fixed to an upper part of the bridge; an upper plate which is to be coupled to a lower part of the girder and separated at a certain distance from the lower plate; an elastic pad which is prepared between the lower plate and the upper plate; and a movable stopper which is arranged on the lower part of the upper plate and the upper part of the lower plate, respectively, at a certain distance from the elastic pad in the direction perpendicular to bridge of the elastic pad. The movable stopper comprises a coupling unit which is coupled to the upper plate or the lower plate for moving; and a stopper unit which is protruded from the coupling unit. |
