         5 . The washing machine according to  claim 1 , wherein:
 at a position closer to an upstream side than the inflow ports of the circulating water path, at least near the inflow ports, a width of the water path from the side surface of the washing and dewatering drum to a direction of the filter unit is gradually decreased as closer to the inflow ports.   
     
     
         6 . The washing machine according to  claim 2 , wherein
 the filter unit comprises a first member for forming the outflow port and a second member for forming the inflow port;   the first member and the second member are connected in a manner of being separated in front and rear directions, and   on the second member, an eave-shaped protrusion body protruding towards the rear is arranged at a position closer to upper side than the inflow port.   
     
     
         7 . The washing machine according to  claim 2 , wherein:
 the filter unit is inclined in a manner of inclining to a side surface of the washing and dewatering drum in a state of being mounted on the circulating water path.   
     
     
         8 . The washing machine according to  claim 7 , wherein
 at a position closer to an upstream side than the inflow ports of the circulating water path, at least near the inflow ports, a width of the water path from the side surface of the washing and dewatering drum to a direction of the filter unit is gradually decreased as closer to the inflow ports.   
     
     
         9 . The washing machine according to  claim 7 , wherein:
 a turning body for turning a water flow which will flow to upper sides of the inflow ports into a water flow towards the inflow ports is arranged in the circulating water path.   
     
     
         10 . The washing machine according to  claim 9 , wherein:
 at a position closer to an upstream side than the inflow ports of the circulating water path, at least near the inflow ports, a width of the water path from the side surface of the washing and dewatering drum to a direction of the filter unit is gradually decreased as closer to the inflow ports.   
     
     
         11 . The washing machine according to  claim 2 , wherein:
 a turning body for turning a water flow which will flow to upper sides of the inflow ports into a water flow towards the inflow ports is arranged in the circulating water path.   
     
     
         12 . The washing machine according to  claim 11 , wherein:
 at a position closer to an upstream side than the inflow ports of the circulating water path, at least near the inflow ports, a width of the water path from the side surface of the washing and dewatering drum to a direction of the filter unit is gradually decreased as closer to the inflow ports.   
     
     
         13 . The washing machine according to  claim 3 , wherein:
 a turning body for turning a water flow which will flow to upper sides of the inflow ports into a water flow towards the inflow ports is arranged in the circulating water path.
