Abstract

A laundry machine (100) includes a tub (20) in a cabinet ( 10) for holding washing water and a motor (40) is provided a a rear of the tub (20) for rotating the drum (30). The motor (40) includes a stator (44) and a rotor (42), and a vibration/noise transfer preventive unit is part of the stator (44). The stator (44) has a coil unit (445) and an insulator (450) for mounting the coil unit (445) thereto. The insulator (450) has a plurality of teeth (446). The transfer preventive unit includes a plurality of tub fastening portions ( 193; 293), a plurality of deformation portions ( 191; 291 ) and connection portions ( 192; 292). At least one introducing portion (294) is provided to the tub fastening portions (293) or deformation portions (291).
