Claims

[Scope of utility model registration request]

(1) A pressure contact member that presses against the rotation shaft to fix the tension frame to the rotation shaft, a tension member that operates the pressure contact member to tighten the tension frame, and a tension member that drives the tension member. a fixed operation means, and a fine movement means for rotating the tension frame about the rotation shaft to slightly rotate the rotation shaft, and a rotating part of the tension means and the tension operation means. The rotational shaft fine adjustment device is characterized in that the rotational shaft fine adjustment device is connected with a universal joint by a universal joint, and the fine adjustment means is inserted along the inner shaft of the tension operation means.

(2) The tensioning means moves the pressing means in a direction intersecting the axial direction of the rotating shaft, and a moving means that moves in the moving direction, and a moving means that moves the moving means by rotational action in a direction that intersects with the moving direction. 2. The rotating shaft fine movement device according to claim 1, further comprising: a rotating part having a rotating shaft; and a rotating part having a rotating shaft.

(3) a pressure contact member, a bushing rod that moves the pressure contact member in a direction substantially perpendicular to the axial direction of the rotating shaft, and a bushing rod that moves in the moving direction; and a rotating shaft that moves the bushing rod in a direction substantially perpendicular to the moving direction. an eccentric cam having a rotational axis of the eccentric cam is attached to the tension frame, and the fine movement means presses the eccentric cam in substantially the same direction as the rotational axis direction of the eccentric cam by its fine movement feeding operation, thereby tightening the tension frame. The rotational shaft fine movement device according to claim 2, which is characterized in that the rotational shaft is slightly rotated about the rotational shaft. -(4) A lever means is interposed between the bushing rod and the eccentric cam, the lever having a rotation axis substantially parallel to the rotation axis of the eccentric cam and being rotated in and out by the eccentric cam. A rotating shaft fine adjustment device according to claim 3 of the patented utility model.
