PROBLEM TO BE SOLVED: To obtain a roller support body, capable of having further ease of an attachment, and preventing occurrence of ununiformity for pressure contact force between a driven roller and a driving roller. SOLUTION: A torsion coil spring 55 energizing a conveyance driven roller holder 50 is disposed so that the axial direction of a coil part 55a may become in a direction orthogonal to the axial direction of conveyance driven rollers 4. A protrusion 10b protruded in a direction parallel to the axial direction of the coil part 55a is formed at a frame bent part 10a in which the conveyance driven roller holder 50 is attached. The conveyance driven roller holder 50 is attached by engaging the coil part 55a with the protrusion 10b in a straight line condition, thus improving ease of the attachment. Additionally, a spring end 55b energizes the proximity of the two conveyance driven rollers 4, and a load can be uniformly applied to the two driven rollers for conveyance. COPYRIGHT: (C)2004,JPO
