PROBLEM TO BE SOLVED: To provide a friction implement which can thermally discolor only a part to be targeted and erased even in a large area or a small area of a handwriting with thermochromic ink on a paper surface, and can prevent a friction part of a friction body from getting dirty.SOLUTION: Friction parts are arranged on front and rear ends of a friction body. A window part, from which the friction body can be slid with a finger and which extends in a longitudinal direction, is arranged on a side surface of a case body. A plurality of ribs extending in the longitudinal direction or projections continuing in the longitudinal direction are formed on an inner side surface on an opposite side to the window part of the case body. The friction body is housed in a through hole of the case body. When the friction body exposed from the window part of the case body is pushed, the friction body is made to slide-contact with the plurality of ribs or projections, and the friction part is delivered from an opening part on a front side or a rear side of the case body.SELECTED DRAWING: Figure 1 |
