Abstract
Disclosed herein is a damper for use in a drum type washing machine, which can support a tub of the washing machine and absorb vibration of the tub. The damper comprises a cylinder, a piston partially inserted inside the cylinder, and a fixed damping member and movement prevention means, which are installed around an inserted portion of the piston inside the cylinder so that they are spaced apart from each other, and adapted to allow the piston to be stably supported inside the cylinder even in case that a tub of the washing machine vibrates in a non-axial direction of the cylinder and piston, thereby restricting a relative angular rotation of the cylinder and piston and preventing rubbing and collision caused between a lower end of the cylinder and the piston.
