PURPOSE:To prevent the seizure of the bearing even when a rotary shaft short in lubricating water by embedding a non-lubricating liquid bearing material such as a tetrafluoride resin in a rubber body of a rubber bearing so that a part of the bearing material is exposed to the bearing surface. CONSTITUTION:A strip 3 of a semicylindrical shape formed into a segment type by a rubber 4 is fixed to a bearing outer cylinder 2A through a bolt 6. Further, within the strip 3 is embedded a plate member 5 having a hole through which the bolt 6 fixing the strip 3 penetrates. In this plate member 5 are provided holes 5a each having a slightly large diameter. In each hole 5a is embedded a bearing bush 7 of a tetrafluoride resin, the upper body of which is of a columnar shape and the lower body of which is a large-diameter disc shape. The top surface of the bearing bush 7 is exposed on the same plane as the bearing surface of the rubber 4. |
