 a current plate member;    an azimuth pod fixed to a lower portion of said current plate member, said azimuth pod being provided with a propeller member, and said current plate member and said azimuth pod being provided so as to be rotatable together along a vertical axis with respect to the bottom of a ship; and    an auxiliary steering member provided with said current plate member.    
     
     
         2 . An azimuth propeller device according to  claim 1 , wherein said auxiliary steering member is a rear flap member rotatably attached to a trailing edge portion of said current plate member.  
     
     
         3 . An azimuth propeller device according to  claim 1 , wherein said auxiliary steering member is a front flap member rotatably attached to a front edge portion of said current plate member.  
     
     
         4 . An azimuth propeller device according to  claim 1 , wherein said auxiliary steering member is a front flap member rotatably attached to a front edge portion of said current plate member, and a rear flap member rotatably attached to a trailing edge portion of said current plate member.  
     
     
         5 . An azimuth propeller device, comprising: 
 a current plate member ;    an azimuth pod fixed to the lower portion of said current plate member, said azimuth pod being provided with a propeller member, and said current plate member and said azimuth pod being provided so as to be rotatable together along a vertical axis with respect to the bottom of a ship;    a vertical stabilizer disposed at a lower portion of said azimuth pod; and    a trailing edge flap member rotatably attached to a rear edge portion of said vertical stabilizer.    
     
     
         6 . An azimuth propeller device according to  claim 1 , wherein 
 said auxiliary steering member is a pair of open-close flap members attached to a side wall portion of said current plate member, said pair of open-close flap members being disposed so as to be opening and closing independently.    
     
     
         7 . An azimuth propeller device according to  claim 6 , wherein said pair of open-close flap members are fully opened to make an emergency stop of a ship.  
     
     
         8 . An azimuth propeller device according to  claim 1 , wherein 
 said auxiliary steering member set forth in any one of claims  2 - 4  is combined with said auxiliary steering member set forth in  claim 6  or  7 .    
     
     
         9 . An azimuth propeller device according to  claim 5 , further comprising: 
 a pair of open-close members attached to a side wall portion of said vertical stabilizer, said pair of open-close flap members being disposed so as to be opening and closing independently.    
     
     
         10 . An azimuth propeller device according to  claim 1 , further comprising: 
 at least one radiation member provided at an outer periphery of said azimuth pod, wherein 
 said propeller member is a POD propeller member and a motor which drives said POD propeller member is provided inside said azimuth pod.  
   
     
     
         11 . An azimuth propeller device according to  claim 10 , wherein 
 said auxiliary steering member set forth in any one of claims  2 - 4  is combined with said auxiliary steering member set forth in  claim 6  or  7 .    
     
     
         12 . An azimuth propeller device according to  claim 10 , wherein said radiation member is a fin extending in the front and back direction of said azimuth pod.  
     
     
         13 . An azimuth propeller device according to  claim 12 , wherein said fin is twisted in the rotation direction of said POD propeller member from the front to back of said fin.  
     
     
         14 . An azimuth propeller device according to  claim 5 , further comprising: 
 at least one radiation member provided at an outer periphery of said azimuth pod, wherein 
 said propeller member is a POD propeller member and a motor which drives said POD propeller member is provided inside said azimuth pod.  
   
     
     
         15 . An azimuth propeller device according to  claim 14 , further comprising: 
 a pair of open-close members attached to a side wall portion of said vertical stabilizer, said pair of open-close flap members being disposed so as to be opening and closing independently.
