Abstract: A blow-out oil reduction type vacuum pump in an engine is provided to prevent blow over even during severe conditions including conventional drive conditions. A blow-out oil reduction type vacuum pump in an engine includes a housing(11), a guide part(14), an expansion part(15), and a cut part(16). The housing accommodates a rotor. A coupler is connected to a vacuum pump connected to a cam shaft to rotate the rotor of the vacuum pump. An oil supply hole is formed at a center of the coupler to lubricate the interior of the vacuum pump. The guide part has a plate shape and is sealed around the housing at a lower end of the coupler. The expansion part expands the housing in an axial direction of the housing to fix the guide part by fitting and mounting an outer surface of the guide part into an inner surface of the housing. The cut part is configured to drain oil through a slot formed around the guide part.
