To provide a device to solve a problem that at most a single futon can be hung on a balustrade of veranda when wet clothes are hung out, and there is a concern that when a washed and wet futon is hung on the balustrade of veranda, the futon may get dirty by dirt of an outer wall of the veranda.

A space-saving laundry device has a belt to fix a laundry pole to a balustrade of veranda (or an existing laundry pole) and a board to keep the laundry pole away from the balustrade of the veranda or an outer wall. The device can be placed in a dedicated case to be stored on a bookshelf, etc. when not in use.
