<p><P>PROBLEM TO BE SOLVED: To prevent a driving wheel from getting deformed. <P>SOLUTION: The rotary drum display device is structured so as to rotate a pattern display body by rotationally driving the driving wheel 11 by a motor by winding an endless strip-shaped pattern display body around the driving wheel 11 and a driven wheel. In the rotary drum display device, the driving wheel 11 is equipped with a cylinder (end cylinder 12) contacting the pattern display body, and a rotating center (motor shaft mounting portion 17) to which the rotating shaft of the motor is mounted and forming the rotating center of the driving wheel and a supporting member 3 mutually connecting the cylinder and the rotating center. The supporting member 3 has a width W in the direction parallel with the rotating shaft larger than a thickness H in the direction orthogonal to the rotating shaft. <P>COPYRIGHT: (C)2004,JPO</p> |
