Abstract (en)

A drum type washing machine, and a method for assembling its shaft system (30) are disclosed. The shaft system (30) comprises a flange shaft (31) coupled to a rear side of the drum (12) to transmit the rotational force of the motor (20) to the drum (12). A buffering material (40) is provided between the drum (12) and the flange shaft (31) to distribute or absorb load or vibration transmitted from the drum (12) to the flange shaft (31). The buffering material (40) comprises a material having a liquid phase initially and changing to a solid phase having elasticity a predetermined period of time after contacting air. The buffering material (40) is applied to a rear side of the drum (12) or to a rear side of the flange shaft (31) when assembling the shaft system (30).
