Abstract: 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.

Abstract: In a vehicle lower portion structure, a plurality of cross members are suspended along a vehicle width direction between a pair of side rails. Further, an oil pan guard is suspended along a longitudinal direction between a No. 2 cross member and a No. 3 cross member to protect an oil pan of a transmission from below. When a vehicle collides on its front, engagement between the oil pan guard and the cross member is released, to thereby prevent a decrease in the amount of collision energy to be absorbed by the pair of side rails.

Abstract: A breather device for a casing structure of a vehicular power transmitting system including an electric motor and a transmission, the casing structure having motor and transmission accommodating casings, the breather device including first and second breather apertures formed in communication with inside spaces, and a breather outlet communicating with an outside atmosphere outside the casings, the first and second breather apertures permitting flows of air from the inside spaces within the casings, into the outside atmosphere through the breather outlet, to prevent an excessive rise of air pressures within the inside spaces, the breather device including a communication conduit for communication between the first and second breather apertures, and a single breather conduit held in communication at one of its opposite ends with the communication conduit and at the other end with the breather outlet, whereby the inside spaces are open to the outside atmosphere.
