PURPOSE:To improve a damping effect as a squeeze film damper while reducing a shaft distance of a rotary shaft to the possible minimum level. CONSTITUTION:A double cylinder type bearing case 8 having an annular space part 9 in a concentrical form with a rotary shaft 1 is arranged on the outer peripheral side of a bearing 7 on which the rotary shaft 1 is pivoted rotatably, and a cylindrical part 10 projecting from a bearing housing 5 is arranged in the annular space part 9 in a condition where shaft directional end parts of clearances 13 and 14 are sealed up while interposing the oil film forming clearances 13 and 14 between the inner and the outer peripheries. |
