<p>PROBLEM TO BE SOLVED: To provide a curl cord prevented from occurrence of twisting.SOLUTION: A curl cord is formed from a deformed flexible cord 10, having a curl part 22a which is retained in an approximately cylindrical shape in a non-loaded state and can be stretched responding to a load in a pulling direction. The cord 10 is folded along the circumferential direction of the peripheral surface of a virtual cylindrical body into a zigzag shape so as to form a carl part 22a. In a non-loaded state of the curl part 22a, the folded parts 31 adjacent to each other of the cord 10 are arranged along a straight line and the folded parts 31 opposed to each other are separated at a predetermined distance.</p> |
