A hose continuous in series throughout an entire length integrally formed with a water-intake port, L-shaped bending part, an intermediate part and a drain port in this order from one end of the hose to the other. The substantially general part of the intermediate part is formed with corrugations having inclined side walls of unequal length which are constructed so that shorter inclined walls can be easily brought into their contracted positions substantially parallel to the longer inclined walls and they can self hold their positions. The hose has such a length that the substantially whole length thereof can be housed in an outer casing of a washing machine in its contracted state.
