<p><P>PROBLEM TO BE SOLVED: To provide a vibration damping mechanism capable of providing a sufficient damping force at low revolution of a rotary shaft while suppressing an excessive damping force at high revolution, with no growth in diameter or size of the rotary shaft. <P>SOLUTION: A rotary shaft 2 of the vibration damping mechanism is provided with a flange 4 which is stored in a housing 5 filled with viscous fluid 6. The vibration damping mechanism comprises a movable stirring resistor 22 which is so provided in the flange 4 for rising and setting as to be housed in the flange 4 by the centrifugal force caused by rotation of the rotary shaft 2, and an elastic body 24 which energizes the stirring resistor 22 so that the stirring resistor 22 protrudes from the flange 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
