<p>PURPOSE:To enable a conveyer line, having a curve, to be relatively easily constituted and enable a roller to be raced, by providing a synchronous motor in an outer cylinder, in the case of the roller for a conveyer constituted by axially rotatably supporting the outer cylinder to fixed shafts through bearings. CONSTITUTION:This roller 1 has fixed shafts 2, 3 on the same axis and an outer cylinder 5 axially rotatably supported to the both fixed shafts 2, 3 through bearings 4.... While the roller 1 is constituted by providing a motor 6 placing aside to a side of the one fixed shaft 2 in the outer cylinder 5 so as to enable it to be rotated at a reduced speed through planetary gears 7 by rotating the motor 6. This motor 6 is constituted by fitting a rotor 9, including two rotor members 9a, 9b consisting of a permanent magnet, to be fixed to a driving shaft 8, rotatably provided independently of the fixed shafts 2, 3, and by providing a stator 10, consisting of two stator members 10a, 10b, so as to envelop said rotor 9 from both sides, and the stator 10 is fixedly provided to the fixed shaft 2.</p> |
