PROBLEM TO BE SOLVED: To restrain increase of friction between a pressing roller and a disc due to displacement of a rotation shaft of a pressing roller and a shaft coupling line because of variation of a dimension.SOLUTION: A multi-disc transmission 3 comprises: a roller support frame 22 rotatably supporting a pressing roller 13; and a trunnion 23 for swingably supporting the roller support frame 22 with a pin 25 orthogonal to disc faces of a primary disc 11 and a secondary disc 12 as a center nearer a position at which the primary disc 11 and the secondary disc 12 start overlapping than a position at which the pressing roller 13 contacts the primary disc 11 and the secondary disc 12. |
