         10 . The washing machine according to  claim 9 , wherein the fixing protrusion includes an expanded anti-separation portion provided at a distal end thereof and configured to be tapered away from the front surface of the tub. 
     
     
         11 . The washing machine according to  claim 10 , wherein the second close-contact portion is provided with a fastening hole for fastening with the at least one fixing protrusion. 
     
     
         12 . The washing machine according to  claim 11 , wherein the tub includes a seating recess to allow the circulation hose to be seated in the front surface of the tub. 
     
     
         13 . The washing machine according to  claim 1 , wherein the tub includes at least one protruding rib provided at a lateral surface thereof, and the at least one protruding rib includes a supporting plane to support the circulation hose. 
     
     
         14 . A washing machine comprising: a cabinet; a tub placed in the cabinet; a circulation pump placed beneath the tub; and a circulation hose connected to the circulation pump and serving to supply wash water, pumped by the circulation pump, into the tub,
 wherein the tub includes a seating recess to allow the hose to be seated in a front surface of the tub, and   wherein a pressure member to press the hose seated in the seating recess is coupled to the front surface of the tub.   
     
     
         15 . The washing machine according to  claim 14 , wherein the pressure member is a weight-balance. 
     
     
         16 . The washing machine according to  claim 15 , wherein the pressure member includes an accommodation portion to receive a part of the hose therein. 
     
     
         17 . The washing machine according to  claim 16 , wherein the accommodation portion includes a pressure plane to press the hose to allow the hose to come into close contact with the seating recess. 
     
     
         18 . A washing machine comprising:
 a cabinet defining an outer appearance of the washing machine;   a tub placed in the cabinet;   a circulation pump placed beneath the tub;   a connection hose connected to the circulation pump and serving to supply wash water, pumped by the circulation pump, into the tub;   a circulation hose having one end connected to the connection hose and serving to provide the wash water moving in the connection hose with air; and   a holder provided at a position of the tub to fix the circulation hose,   wherein the holder includes: at least one fixing protrusion protruding from a front surface of the tub; a guide rib protruding from the front surface of the tub around the fixing protrusion;   and a hook coupled with the at least one fixing protrusion.
