Claim 0:
1. A device for pivotably supporting a return roller in a frame-fixed articulation region of a belt conveyor having a transport belt that circulates over the return roller in a running direction (L), the device comprising:
a pivot arm that extends in the running direction, which is orthogonal to a longitudinal axis of the return roller, the pivot arm rotatably supporting the return roller about the longitudinal axis;
a pivot element of the pivot arm that is spaced apart from the return roller in the running direction;
a pivot bearing, arranged on the articulation region for mounting the pivot element, allowing a pivoting movement of the pivot arm between an operating position of the return roller and a nonoperating position of the return roller, about a pivot axis that is parallel to the longitudinal axis, wherein the pivot bearing has a bearing surface in the form of an open arc, in a section perpendicular to the pivot axis, an opening of which appears at a center angle (φ) of less than 180° ;
a sliding body, formed on the pivot element, which, in a pivot position range containing the operating position, is rotatably guided on the bearing surface while fixed on the articulation region and which can be passed through the opening in the nonoperating position; and
a passage channel for the sliding body extending from the opening to a free outlet that is formed in the articulation region.
