たは第(3)項記載の蛇行検出装置。[Claims for Utility Model Registration] (1) A meandering detection device for detecting meandering of a flat belt running between a plurality of roller members, wherein each roller member supports a roller on a support shaft. At least one of the roller members is configured as a meandering detection roller member, and at least one spindle end of the meandering detection roller member is disposed coaxially with the meandering detection roller member. A meandering detection member is provided which is rotatably supported independently of the meandering detection roller member and is rotatable in contact with the meandering flat belt, and the meandering detection member is capable of contacting the flat belt. A meandering detection device characterized in that a run-on portion is formed, and the run-up portion is made of an elastic material. (2) The meandering detection device according to claim 1, wherein the elastic material forming the riding part of the meandering detection member is polyurethane. (3) The meandering detection device according to claim 1, wherein the elastic material forming the riding part of the meandering detection member is NBR. (4) Utility model registration claim No. (1), (2) or (3) characterized in that the elastic material constituting the riding part of the meandering detection member contains organic short fibers. Meandering detection device described in Section 1.
