Abstract
A damper includes a cylinder, cores and covers. The cylinder includes eccentric bores each confined in a wall formed with a thick portion and a thin portion located opposite to the thick portion. The thick portions of the eccentric bores are located on different sides of the cylinder. Each core is inserted in a corresponding eccentric bore. The covers close the eccentric bores to keep the cores in the eccentric bores. The cores are made with a volume smaller than that of the eccentric bores. The cores are separated from each other. The cores exert forces on the walls of the eccentric bores because of inertia to alleviate vibration of the cylinder.
