PURPOSE:To improve an operability by providing a slider for containing a cord on a case so as to be freely slidable, so that said cord can be contained in said case by a movement of the slider. CONSTITUTION:As for a slider 11, a freely turnable roller 28 is provided on the rear end of its upper part, a flexible cord 10 is made to pass through a hollow 29, and also a small uneven part for a slide-stop is formed on a lower face 11a. Also, the slider 11 can be moved along a slide groove 13 of a case 5 by pressing a finger, etc. against its lower face. Accordingly, in case of installing an eraser head part 8 to the case 5, when a finger, etc. are pressed against the lower surface 11a of the slider 11, and it is moved to the inner part side of the case 5, the cord 10 is contained into the case 5 smoothly and without being loosened, by a rotation of the roller 28, and in this way, the operability can be improved. |
