<p>A balance shaft unit is provided to improve stability and facilitate assembly by manufacturing a housing element of a thin wall and reducing the number of components of an oil pump balance shaft module. A balance shaft unit comprises: one or more balance shafts(14) having one or more balance weights(18); a housing element(30) accepting the balance shaft; and a first gear(26) being coupled on the balance shaft and engaging with the second gear(28). The housing element comprises one or more fitting openings(32). The housing element comprises an induction path(33) which induces one or two gears inside the housing element. The induction path perpendicularly extends in a longitudinal axis(36) of the balance shaft. The first and the second gear are consecutively arranged in the extension direction of the induction path.</p> |
