徴とする請求項(1)記載のリターンローラ装置。[Claims for Utility Model Registration] (1) A roller support member rotatably supported around an axis at both ends and having a circumferential protrusion on the outer circumferential surface, which is removably inserted into the roller support member. A return roller device for a belt conveyor includes a plurality of return rollers arranged in a row, and a portion of the conveyor belt on which a conveyed object is not placed is supported by a protrusion on the outer circumferential surface of the return roller. A pair of return rollers facing each other at a certain distance are provided near both ends of the support member in the axial direction, and rollers each having an outer diameter approximately the same as that of the protrusion are provided so as to straddle between the pairs of return rollers. A return roller device characterized in that hollow guide rollers are provided concentrically, and the ends of the conveyor belt in the width direction are respectively supported by the pair of return rollers and the guide rollers. (2) The roller support member is a hollow cylindrical member, and is disposed at both ends of the bearing case of a pair of bearings that rotatably support the roller support member. A metal sleeve is assembled to at least one of the bearing cases, and at least one end of the roller support member is integrally fixed to the metal sleeve by caulking inward in the radial direction to the bearing case. 2. The return roller device according to claim 1, wherein the return roller device is attached.
