<P>PROBLEM TO BE SOLVED: To provide a vibration control structure of the joint part which can suppress the vibration more effectively while avoiding the damage of the structure. <P>SOLUTION: The vibration control structure has first and the second members which moves relative to each other in a predetermined direction, a third member which sandwiches the first member along with the second member, and a crimping power energizing member which is stacked on the first, second and third members, deformed and compressed by stacking, and energizes the crimping power to the first, second and third members. The vibrational energy is absorbed by the frictional force which is produced when the second member, the third member and the crimping power energizing member displace relative to the first member by the vibration. The crimping power energizing member has a characteristic that the crimping power increase sharply when it begins to deform in the compression direction from the relaxed direction, and the crimping power decreases sharply when changing to the relaxed direction which the compression is tempered and begins to change, and when the relative displacement exceeds the predetermined range, the compression of the crimping power biasing member is relaxed from the time of relative displacement within the predetermined limit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
