         8 . The suction tool for an electric cleaner of  claim 2  further comprising a plate made of a material listed in the negative side of the triboelectric series is provided on an outer periphery of the friction body. 
     
     
         9 . The suction tool for an electric cleaner of  claim 3  further comprising a plate made of a material listed in the positive side of the triboelectric series is provided on an outer periphery of the friction body. 
     
     
         10 . The suction tool for an electric cleaner of  claim 8 , wherein
 the plate is provided protruding from a surface of the friction body.   
     
     
         11 . The suction tool for an electric cleaner of  claim 2  further comprising a board made of a material listed in the negative side of the triboelectric series is provided on a front part of the suction tool main body on a face opposing the rotary brush. 
     
     
         12 . The suction tool for an electric cleaner of  claim 3  further comprising a board made of a material listed in the positive side of the triboelectric series is provided on a front part of the suction tool main body on a face opposing the rotary brush. 
     
     
         13 . The suction tool for an electric cleaner of  claim 1  further comprising a holding part is provided for detachably holding the friction body on the suction tool main body. 
     
     
         14 . The suction tool for an electric cleaner of  claim 13 , wherein
 the holding part is provided inside the suction inlet of the suction tool main body such that the holding part forms a part of the suction inlet.   
     
     
         15 . The suction tool for an electric cleaner of  claim 13 , wherein
 the holding part includes a buckle for detachably fixing the holding part onto the suction tool main body.   
     
     
         16 . The suction tool for an electric cleaner of  claim 13 , wherein
 the friction body includes a friction main body and a shaft protruding from the friction main body for rotatably supporting the friction main body, the shaft including an insert on its one end and a holder on its other end;   the insert of the shaft of the friction body is held by the suction tool main body, and the holder of the shaft is held by the suction tool main body using the holding part; and   a length of the holder of the shaft is longer than a length of the insert of the shaft.   
     
     
         17 . The suction tool for an electric cleaner of  claim 16  further comprising a rotation stopper is provided on one side of the shaft having the holder.
