To provide a center bearing support structure which can properly seals a center bearing according to a rotation number of a propeller shaft.SOLUTION: A center bearing support structure comprises a seal member 16 which seals an outer periphery of a propeller shaft 10, and a moving member 20 which is movable in axial direction of the propeller shaft 10 and is brought into contact with the seam member 16. A seal portion 23 of the moving member 20 is held in a state in which the seal portion is brought into contact with the seal member 16 during low speed rotation of the propeller shaft 10, the seal portion 23 of the moving member 20 is so moved as not to be brought into contact with the seal member 16 by movement of a weight ball 31 due to centrifugal force of the weight ball 31 during high speed rotation of the propeller shaft 10.SELECTED DRAWING: Figure 1

    【課題】プロペラシャフトの回転数に応じて、適正にセンターベアリングのシールを行うことのできるセンターベアリングサポート構造を提供する。【解決手段】プロペラシャフト10の外周におけるシールを行うシール部材16と、プロペラシャフト10の軸方向に移動自在とされ、シール部材16に接触する移動部材20とを備え、プロペラシャフト10が低速回転時は移動部材20のシール部23をシール部材16に接触させた状態に保持し、プロペラシャフト10が高速回転時は、ウエイトボール31の遠心力によるウエイトボール31の移動により移動部材20のシール部23をシール部材16と接触させないように移動させる。【選択図】図1
