摘要： A power transmission apparatus for press machine according to the invention transmits rotational power from a drive shaft to a driven shaft. The apparatus has at least two drive gears arranged along an axial direction and substantially integrally attached to the drive shaft, a driven gear substantially integrally attached to the driven shaft, and an idle gear rotatably supported on an idle shaft and having a gear meshing with the driven gear and a plurality of gears corresponding respectively to the at least two drive gears. The idle gear can be displaced relative to the drive gear along the axial direction of the idle shaft to cause one of the at least two drive gears and corresponding one of the plurality of gears of the idle gear to mesh with each other selectively.
