<P>PROBLEM TO BE SOLVED: To provide a friction implement and a thermochromism writing utensil which make it unnecessary to shift a writing utensil body greatly from one hand to the another and enable quick transfer to a frictional thermochromism operation when performing thermochromism of an image or handwriting by friction after writing. <P>SOLUTION: The friction implement rubs the thermochromism image or handwriting formed on a writing object surface by means of thermochromic ink and can attain thermochromism of the image or handwriting by the frictional heat generated in rubbing. The friction implement includes a holding part 2 which has an inner hole 21 through which a finger can be inserted for holding, and a friction part 3 which is provided on the outside of the holding part 2 and consists of an elastic material capable of rubbing the thermochromic image or handwriting. <P>COPYRIGHT: (C)2012,JPO&INPIT |
