<P>PROBLEM TO BE SOLVED: To provide a thermally changeable color writing tool that houses thermally changeable color ink and can easily discolor the thermally changeable color writing by friction and also can promptly make a writable state (pen point projected state) or a storage state (pen point retracted state) even if only one hand can be used. <P>SOLUTION: The thermally changeable color wiring tool containing a thermally changeable color ink, includes: a writing body 8 that accommodates thermally changeable color ink inside; a barrel 2 that movably accommodates inside the writing body 8 in a back and forth direction; an operating part 5 for projecting/retracting the pen point 81 from/into the front end hole 31 of the barrel 2 of the writing body 8; and a friction part 4 that is made of low abrasive elastic materials and can thermally change the color of the writing by frictional heat generated when the writing of the thermally changeable color ink is rubbed, and the friction part 4 is provided at the outer face of the operating part 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
