摘要：
A damper for a washing machine includes: a cylinder; a piston body having one end inserted into the cylinder; a first friction member interposed in a contact surface between the piston body and the cylinder; an extension bar extended from an inserted portion of the piston body, the extension bar having a circumferential stopper at the extended portion; a friction ring formed between the circumferential stopper and the first friction member; and a second friction member formed on an outer circumferential surface of the friction ring to contact with an inner surface of the cylinder.
