Definitions

  • the tub may be formed to be closer in the lateral direction to the wall or the frame than the drum.
  • the tub may be spaced away from the wall or the frame by an interval of less than 1.5 times an interval with the drum.
  • the drum may also be enlarged in the lateral direction.
  • the drum may be expanded in the lateral direction in direct proportion.
  • the vibration of the drum in the lateral direction may be considered. The weaker the vibration of the drum in the lateral direction, the more expanded is the diameter of the drum.
  • a stator 80 is fixedly secured to the bearing housing 400 and the rotor is located around the stator 80 . As mentioned above, the rotor is directly connected to the shaft 351 .
  • the motor is an outer rotor type and it is directly connected to the shaft 351 .
  • the middle portions 431 e and 430 e are extended toward the radial direction, with maintaining the identical angle to the angle of the first and second coupling parts 430 d and 431 d, and they are curved downward to meet the bracket connecting portions 4301 c and 430 c.
