<p><P>PROBLEM TO BE SOLVED: To provide a bag with rollers, positioned on the side of the body of a towing person and lightly towed in the state of reducing the fully occupying area around the bag including the towing person. <P>SOLUTION: The roller 2 is rotated round the lateral axis intersecting the major axis direction of a case body 1 so that the bag is towed with the major axis direction of the case body 1 along the longitudinal direction, and a handle 3 formed of hard material to control the attitude of the case is positioned so that a segment y1 connecting a grip part 32 thereof and the grounding point O of the trunk roller is rather closer to a segment y2 connecting the grounding point O and the center of gravity G of the case body with a range of angle made between the front edge of the forward tilting attitude of the case body 1 and the segment y2. Further, the grip part 32 in the reference towing attitude is set to position at the same level as the grip position of the hand naturally hanging down. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
