PROBLEM TO BE SOLVED: To reduce space, make a structure simpler, and improve reliability by forming a gap for oil damper between a fixed wall and a rotating wall and forming an oil film by filling the gap with oil and immersing the fixed wall and the rotating wall into oil in an oil storaging part. SOLUTION: A first oil damper gap δa is formed between a fixed wall 11 integrated with a housing 5 of a fixed side and a rotating shaft 4 integrated with a rotating shaft 4 and oil 15 filling the gap forms an oil film to damp the vibration in a radial direction of the rotating shaft 4. A second oil damper gap δb is formed to damp the vibration in a thrust direction of the rotating shaft 4. An oil circulation mechanism is not necessary by immersing the fixed wall 11 and a rotating wall 12 into the oil 15 in an oil storaging part to make the device compact, thereby reducing space and making structure simpler and improving reliability and reducing cost. |
