。 In the pressure contact support structure for a pair of rolls, the support member rotatably supports the pair of rolls, and the compression spring pressurizes one roll against the other roll. At least the end opposite to the pressing roll is movably held, and the length of the compression spring in the expansion/contraction direction is set to a first length that provides a predetermined elastic force and a second length that is longer than the first length. a holding hole having a size that can be changed in at least two ways; and a locking protrusion that is protruded at a position that holds the compression spring at the first length and locks the end of the compression spring. Equipped with
A press-contact support structure for a pair of rolls, wherein the end portion of the compression spring is moved along the holding hole, compressed to the first length, and locked to the locking protrusion.
