Abstract:
An input gear, an output gear, an input-side intermediate gear, and an output-side intermediate gear are helical gears. The output gear and the output-side intermediate gear have a larger module than the input gear and the input-side intermediate gear. The input gear and the input-side intermediate gear have a larger twisting angle than the output gear and the output-side intermediate gear. The output gear and the output-side intermediate gear have a larger effective tooth length than the input gear and the input-side intermediate gear.
