An exemplary shock absorber includes a damper tube, a damper piston, a piston shaft, and at least two different surface treatments. The damper tube includes an interior surface. The damper piston includes a piston surface that engages the interior surface. The piston shaft couples with the damper piston and includes a shaft surface that engages a fourth surface. The at least two different surface treatments are disposed on at least one of the interior surface and the shaft surface and create a corresponding plurality of coefficients of friction with at least one of the piston surface and the fourth surface respectively.

A shock absorber for a washing machine and a washing machine having the same are disclosed. The shock absorber includes: a shock absorber sleeve, and the shock absorber sleeve defines an accommodation cavity therein; a shock absorber rod, movably connected to the shock absorber sleeve; an elastic member provided on the shock absorber rod and/or the shock absorber sleeve; a first damping member fitted over the shock absorber rod and mounted on the shock absorber sleeve; and a second damping member mounted on the shock absorber rod and accommodated in the accommodation cavity. The first damping member and the second damping member generate damping when the shock absorber rod moves relative to the shock absorber sleeve. The shock absorber for the washing machine has a simple structure and favorable shock absorbing effects, and occupies little space.

A damper includes: a line-shaped member wound around an outer peripheral surface of a piston which makes a relative motion in a cylinder; and a viscous fluid made to adhere to the line-shaped member and exhibiting viscous damping force. The relative motion of the cylinder and the piston produces tension, and in the line-shaped member, as an amplitude is smaller, its contiguously wound portions each try to deform to twist along a circumferential direction of the line-shaped member itself, and as the amplitude is larger, the contiguously wound portions try to deform as a unit. When the amplitude is small, frictional resistance decreases, resulting in smooth motion of the piston, and appropriate damping force is obtained due to the viscous damping force of the viscous fluid. When the amplitude is large, as a result of the increased tendency that the contiguously wound portions of the line-shaped member try to deform as a unit, friction damping force acts relatively greatly.
