)、第(2)または第(3)項記載の蛇行検出装置。[Claims for Utility Model Registration] (1) A flat belt, a plurality of roller members around which the flat belt is stretched, at least one of which is configured as a meandering detection roller member, and the meandering detection roller member. At one shaft end,
a meandering detection member rotatably supported independently of the meandering detection roller member; and a shaft end portion of the meandering detection roller member on which the meandering detection member is disposed in a predetermined direction perpendicular to the rotation axis. A roller support member that supports movably is connected to a meandering detection member, and when a flat belt contacts the meandering detection member and rotational torque is applied, meandering is detected by converting the rotational motion into linear motion. roller end displacement means for displacing the shaft end of the roller member in a predetermined direction, and in a state where rotational torque due to contact with the flat belt is not applied to the meandering detection member, the flat belt is moved from the meandering detection member to the meandering detection member. The roller member is configured to meander in the direction in which the meandering detection roller member is disposed, and is provided with biasing means for biasing the shaft end of the meandering detection roller member in a direction opposite to the direction of displacement by the roller end displacement means. In the belt drive device, the meandering detection member has a running surface on the outer circumferential surface on which the flat belt can ride, and the running surface is
A meandering detection device characterized in that the contour of a cross section passing through the axis of a support shaft of the meandering detection roller member is inclined to move away from the rotational axis as the distance from the roller of the meandering detection roller member increases. (2) The riding surface of the meandering detection member has a cross-sectional profile passing through the axis of the support shaft, which slopes away from the rotational axis as it moves away from the roller of the meandering detection roller member, and is curved in a concave shape. A meandering detection device according to claim (1) of the utility model registration claim. (3) The end of the meandering detection member facing the roller is formed to have a diameter smaller than the diameter of the roller, as set forth in claim (1) or (2) of the utility model registration claim. Meandering detection device. (4) The meandering detection member is characterized in that a cylindrical portion having the same diameter as the roller of the meandering detection roller member and extending toward the roller is formed on the inside of the riding surface. Meandering detection device according to scope item (1) or item (2). (5) The meandering detection member is characterized in that a small diameter cylindrical portion having a diameter smaller than the diameter of the roller of the meandering detection roller member and extending toward the roller is formed on the inside of the riding surface. Range first (1
), the meandering detection device according to item (2) or item (3).
