Damper

The present invention provides a damper that is capable of minimizing a cylinder with a simplified structure, wherein a spring 76 is mounted over an opening 73 of a cylinder 71 while disposing inclined walls 52, 54 onto two outer faces of a shaft 20 of a piston rod 22, and due to a departing distance of the end faces of the inclined walls 52, 54 is broadened following from a top end of the shaft 20 towards the piston side of the shaft 20, friction resistance is capable of being provided to the piston rod 22 while elastically deforming the spring 76, and thereby a coil spring for assisting damping performance is no longer required, and a minimization of the cylinder 71 is thus feasible. Further, because of direct mounting of the spring 76 over the opening 73, a cap is thus not necessary, and thereby number of parts is able to be decreased while steps with respect to an assembly process is also capable of being decreased, and therefore resulting in a possibility of cost-down achievement.
