Title:
DAMPER DEVICE
Document Type and Number:
Japanese Patent JP3645799
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an innovative damper device being extremely high in a commercial value.
SOLUTION: A shaft 2 is provided to be relatively rotatably inserted in a fitting-in manner in a shaft hole 1a formed in a bearing part 1 and a highly elastic resin part 3, such as urethane and rubber, is located on either the outer peripheral surface of the shaft 2 or the inner surface of the shaft hole 1a or both thereof. A recessed part 4 with which the high elastic resin part 3 makes contact and through which the high elastic resin part 3 is cut is formed in either the inner surface of the shaft hole 1a or the outer peripheral surface of the shaft 2 or both thereof. During relative turning between the shaft 2 and the bearing part 1, cushioning operation due to contact resistance is caused to occur through contact resistance.
