The present invention relates to an apparatus for massive manufacturing a hierarchical structure that can hierarchically form high performance micro units one a flexible substrate. For this purpose, an apparatus for manufacturing a hierarchical structure according to the present invention is provided to layer micro units provided on a dummy substrate that is made of a hard material on a target substrate that is made of a flexible material by releasing the micro units from the dummy substrate. The apparatus includes: a transfer stage flat-transferring the dummy substrate by supporting the same and a main roller rolling the target substrate by winding the same as the transfer stage proceeds and layering the micro unit of the dummy substrate on the target substrate.

A transmission for a vehicle. A rotation force generated in an engine is transmitted via a torque converter to an output shaft. Power of the output shaft is transmitted at a right angle at a bevel gear section that includes a bevel pinion gear and a bevel ring gear. The bevel ring gear transmits power to a clutch unit that includes forward and backward clutch sections to be connected to the bevel ring gear when a speed-change operation is implemented (for example, forward/backward gear shift operations). The clutch unit is connected to a differential gear case, which transmits power to a differential pinion gear and a drive shaft. The vehicle drivable through a reduction gear assembly that is mountable to an axle assembly.
