Abstract
A damper includes a cylinder, a partition member for partitioning the interior of the cylinder into two liquid chambers, an orifice for generating a damping force by flow of liquid, and a bypass path affording communication between the two liquid chambers. The damper further includes a mass body attached to the partition member that is movable in an axial direction of the cylinder and biased to close the bypass path. The speed of the mass body when opening the bypass path is faster than the speed of the mass body when closing the bypass path.
