In a vehicle oil pan guard including a guard plate mounted on a support member via a mounting portion such that the guard plate is arranged at a position under an oil pan storing a hydraulic oil for protecting the oil pan from an impact from below, a cover plate different from the guard plate is mounted together with the guard plate via the mounting portion on the support member such that the cover plate closes an opening formed near the guard plate toward a road surface.

An oil pan for trapping oil of an engine comprising: a curved portion connecting a flat portion and a side wall portion and including a rib-free region where a first reinforcing rib provided on the flat portion and a second reinforcing rib provided on the side wall portion are not connected to each other.

In an oil pan, an outer surface of an oil pan body is covered with urethane foam material. The outer surface of the oil pan body is cation treated to be a surface-treated layer, and the urethane foam material is adhered to the outer surface of the oil pan body by the surface-treated layer without any gaps therebetween. The oil pan further includes an undulating portion formed on the outer surface of the oil pan body and undulating in an inward and outward direction. The surface-treated layer is formed on the undulating portion and the urethane foam material is adhered to the undulating portion without any gaps therebetween. The undulating portion includes a bowl-shaped recess recessed into a bowl shape toward an inner side of the oil pan body and the urethane foam material is adhered to an entire inner surface of the bowl-shaped recess without any gaps therebetween.

An oil pan noise reduction device includes an oil pan, a mounting plate positioned at one side of the oil pan, and a damping member positioned between the oil pan and the mounting plate, in which the mounting plate includes a depressed portion formed in one surface of the mounting plate directed toward the oil pan, and a protruding portion disposed in the depressed portion and protruding from the depressed portion.

A flywheel housing assembly for an internal combustion engine includes a flywheel housing for accommodating a flywheel. The flywheel housing is configured to connect with a part of the internal combustion engine, the flywheel housing further having an outer side region intended to face an oil pan of the internal combustion engine, wherein the outer side region comprises a through hole and a vibration absorbing material portion arranged to seal the through hole.

A non-metallic lubricant pan for a vehicle that includes a body and a structural reinforcement member that is positioned within and secured to the body. The structural reinforcement member includes a drainage column that is generally aligned with a drain hole in the body and ribs that extend between the body and the drainage column such that the drainage column interconnects the ribs.
