Abstract

A trimming machine according to the present invention has a pair of blades each of which has a plurality of cutting edges along a longitudinal direction of the blades and which are reciprocated along the longitudinal direction relative to each other by a rotary power unit. The trimming machine further has a substantially cylindrical eccentric cam eccentrically rotated by the rotary power unit, and a connecting rod having an annular larger end part slidably fitted around the eccentric cam, a smaller end part pivotally attached to one of the blades, and a connecting rod axis passing through a central axis of the smaller end part and a central axis of the larger end part. The larger end part has a bearing portion for bearing load from the blade, and the bearing portion is located on the connecting rod axis when the connecting rod axis is aligned with the longitudinal direction, and is deformable along the connecting rod axis when the bearing portion is subjected to a load.
