PURPOSE: A balance shaft module is provided to save the installation space of an oil pump in an engine room by employing a pumping gear interlocking with a balance shaft in order to implement the function of an oil pump. CONSTITUTION: A balance shaft module comprises a housing(110), a first pumping gear, a second pumping gear, and a pumping unit(130). The housing contains first and second balance shafts which are installed in parallel by first and second drive gears. The first balance shaft is exposed to the outside of the housing and coupled with a sprocket receiving external power. The housing comprises a lower housing and an upper housing. The first and the second pumping gear are connected to each other and feed oil with pressure. The first pumping gear is connected to the first balance shaft so that the first and the second pumping gear interlock with the first and the second drive gear. The pumping unit, in which the first and the second pumping gear are installed, supplies oil to each part of an engine.
