<p>PROBLEM TO BE SOLVED: To easily identify direction of a string-shaped body having direction in the lengthwise direction by attaching a direction indication mark to indicate direction in the lengthwise direction to a flexible thin string-shaped body so as to be seen from outside. SOLUTION: A power source plug 5 is installed on the tip of a cord 3. Plural arrow marks 6 whose tips are turned to the plug 5 side are juxtaposed and attached at proper intervals in the lengthwise direction to an outside surface of the cord 3. Since such marks 6 have independently a direction display function, when a person looks at one of them, he can identify on which side the plug 5 is installed. When positions of the arrow marks 6 are dislocated in order in the circumferential direction, the arrow marks 6 can be visually confirmed even from any direction. Therefore, direction of the cord 3 can be easily identified, and a desired side end part can be correctly pulled out to the hand side.</p> |
