1. A sheet/film forming method using a sheet/film forming roll apparatus including a first roll and a second roll configured to be rotatable in opposition to each other, on each of which a preset pattern is formed, and configured to feed a molten resin into a part between the first roll and the second roll to thereby form a sheet or a film, the method comprising:
rotating the first roll by a first motor;
transmitting a rotation state of a second motor including a rotary portion on which a plurality of permanent magnets are arranged, to the second roll by a power transmission mechanism comprising an intermediate shaft part and two shaft couplings; and
bringing the first roll close to or away from the second roll by a push-pull unit,
wherein
a variation state of a rotating shaft of the second roll created when bringing the first roll close to and away from the second roll is absorbed to be eliminated as the intermediate shaft part is inclined with respect to one of the two shaft couplings as a base point, thereby maintaining a posture of a rotating shaft of the second motor constant at all times,
a shaft direction supporting mechanism configured to support the second roll along a shaft direction in a state where the second roll is rotatable is moved by an axial position adjusting mechanism along the shaft direction and thus the second roll is moved in the shaft direction along the first roll with movement of the shaft direction supporting mechanism, thereby adjusting positions of both patterns on the first roll and the second roll along the shaft direction, and
an adjusting plate of the axial position adjusting mechanism supports the second motor and the power transmission mechanism, wherein the adjusting plate is configured to move the second motor and the power transmission mechanism integrally along the shaft direction.
