1 . A suitcase including:
 a main body adapted to store article therein;   a lid formed at the main body to open and close the main body;   a plurality of annular rotators each surrounding an outer periphery of the main body and rotatably attached to the main body;   a handle fixed to the main body to pull the main body; and   a grounding piece formed at the outer periphery of the main body to keep the main body standing,   the grounding piece comprised of one of:   a grounding piece including a planar grounding area projecting beyond the outer periphery of the main body and being in parallel with a tangent of the outer periphery of the main body; and   a pair of grounding pieces projecting beyond the outer periphery of the main body and being spaced away from each other circumferentially on the outer periphery of the main body so that a length-wise direction thereof is in parallel with an axis of the main body.   
     
     
         2 . The suitcase as set forth in  claim 1 , wherein the main body is cylindrical or polygonal, the rotators being attached to the main body in a circumferential direction of the main body. 
     
     
         3 . The suitcase as set forth in  claim 2 , wherein the lid is formed at at least one of end surfaces situated axially of the main body. 
     
     
         4 . The suitcase as set forth in  claim 2 , wherein the lid is formed at a peripheral surface of the main body.
