A drum type washing machine can enable a shock absorber to effectively move to attenuate and absorb shock of a drum; a spring (5) and hydraulic shock absorbers (6) elastically keep an external tank (3) for holding a drum (2) in a shell (4); the shock of the external tank (3) is attenuated and absorbed by the hydraulic shock absorbers(6) which are connected by a stabilizer (13) on left and right, with a twisted bar part (14) at centre thereof arranged on the shell (4) by a bracket (16) rotatably. When the left and right hydraulic shock absorbers move to and fro in a same (cophase) direction, the stabilizer (13) is rotated by the twisted bar part (14) without generating spring force; when only the hydraulic shock absorbers in one direction move to and fro along with the swinging direction of the external tank (3) , the twisted bar part (14) acts as a torsional spring to make the hydraulic shock absorbers in the other direction move to and fro so as to attenuate force of the hydraulic shock absorbers in the two directions and is combined with the spring force to effectively control the swinging of the external tank (3).
