A vibration isolating structure of an oil pump housing is provided to simplify structure of a damper and to reduce a manufacturing cost by changing the position of a side surface damper member in accordance with the position of a pump assembly. A vibration isolation structure of an oil pump housing comprises a pump assembly(2), a lower damper member(20), and a side surface damper member(30). The pump assembly is driven by a motor assembly(1), pumps up oil, and changes its internal channel direction by using a valve assembly(4) that is controlled by a control assembly(5). The lower damper members are installed at two accumulator assemblies(3) where working fluid is temporarily stored, and have a sealing cover pin(21) and an elastic damper mass(22). The sealing cover pin seal accumulator assembling holes(11,12) are engaged with the accumulator assemblies respectively. The elastic damper mass is fitted to the sealing cover pin. The side surface damper member is located at the side part of the pump assembly and has a bolt(31) and a damper mass(32). The damper mass surrounds the bolt. |
