<p><P>PROBLEM TO BE SOLVED: To provide a portable device strap structure and a portable device with the strap capable of being drawn or wound, having length adjustment and being easily cell-charged. <P>SOLUTION: The portable device is provided with a bearing 15 of a shaft 8 winding the strap 4 and retained by a holder 9 on a board 2 inside a box body, a dynamo 10 driven by turning of the shaft 8 and a spiral spring 14 between the strap 4 and the shaft 8 for providing the shaft with a restoring force to drawing of the strap 4. At the drawing of the strap 4, the drawing length of the strap 4 is adjustable by a winding force of the strap 4 caused by the restoring force of the spring 14 and a frictional force between a stopper 12 and an opening 6 for drawing the strap 4. Rewind can be conducted by the large restoring force obtained through unhanding of a specified drawn state where the spring 14 is fully drawn. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
