。」[Claims for Utility Model Registration] (1) A bearing-cum-aligning inner ring member 2 having a spherical portion 7a with its center O on the axis l of the roller shaft 1 is rotatably fitted onto the outer peripheral surface of the roller shaft 1. An alignment outer ring member 5 is tightly fitted into a cylindrical sleeve 3 having a cylindrical elastic body 4 fixed to its outer circumferential surface, and the bearing is inserted into a spherical annular groove 6 formed on its inner circumferential surface. A pinch roller in which the spherical surface portion 7a of the inner ring member 2 for alignment and alignment is slidably fitted to allow the inner ring member 5 to tilt within a predetermined angular range. (2) The pinch roller according to claim 1, wherein the bearing/aligning inner ring member 2 and the alignment outer ring member 5 are made of hard resin. (3) The alignment outer ring member 5 has a spherical annular groove 6.
The pinch roller according to claim 1, which is registered as a utility model, is comprised of an upper half 5a and a lower half 5b which are divided into upper and lower halves with a horizontal plane where the center O exists as a boundary. The brief description of the drawing has been amended as follows. Replace page 11 of the specification with the attached appendix. "Gender body, 5... Aligning outer ring member, 5a...
