Dual-way mechanical friction type damper and vehicle with damper

The invention relates to a dual-way mechanical friction type damper and a vehicle with the damper. The dual-way mechanical friction type damper comprises a piston cylinder with an end cover, a pistonand a piston rod; the end cover is provided with a guide hole allowing the piston rod to achieve guide sliding penetrating, an elastic body is fixedly arranged on the position, on the inner wall of the piston cylinder, in a rod cavity, the elastic body has an ejecting face which is tightly ejected on the peripheral face of the piston rod so as to enable the piston rod and the ejecting face to generate friction force when the piston rod moves, the ejecting face generates positive pressure on the outer peripheral face of the piston rod, when the piston rod is pulled, certain friction force is generated between the elastic body and the piston rod, through the mechanical friction manner of the mechanism, the function that the piston is parked on the dual-way any position in the piston cylinderis achieved. When the dam
