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.

First claim

What is claimed is:

1. A vehicle oil pan guard comprising:
a pair of mounting shaft members; and
a guard plate mounted across the pair of mounting shaft members on axial intermediate portions of the mounting shaft members, wherein
the vehicle oil pan guard is mounted on a support member via both end portions of the pair of mounting shaft members projected from the guard plate as respective mounting portions in a posture in which the pair of mounting shaft members are spaced apart in a horizontal direction 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, and
a cover plate different from the guard plate is mounted together with the guard plate via the mounting portions on the support member such that the cover plate closes an opening formed toward a road surface between the pair of mounting portions projected from the guard plate in the same side.

2. The vehicle oil pan guard according to claim 1 , wherein
the pair of mounting shaft members is arranged to be spaced apart from each other in a vehicle width direction,
both end portions of the pair of mounting shaft members projected from the guard plate in vehicle front-rear direction are the respective mounting portions, and
the cover plate is disposed across the pair of mounting portions such that the cover plate closes at least one opening formed between the pair of mounting portions projected in at least one of vehicle front and rearward directions.

3. The vehicle oil pan guard according to claim 2 , wherein
a vehicle front side portion and both left and right side portions relative to the guard plate are covered by an undercover different from the vehicle oil pan guard, and
the cover plate is disposed such that the cover plate closes the opening formed in a vehicle rear side portion relative to the guard plate.

4. A vehicle power transmission device comprising
the vehicle oil pan guard according to claim 2 and
an undercover different from the vehicle oil pan guard wherein
the undercover covers a vehicle front side portion and both left and right side portions relative to the guard plate, and
the cover plate is disposed such that the cover plate closes the opening formed in a vehicle rear side portion relative to the guard plate.

5. The vehicle oil pan guard according to claim 1 , wherein
each of the mounting portions has a mounting bolt vertically disposed in a direction perpendicular to a plane parallel to the guard plate and are mounted on the support member via the mounting bolt,
the cover plate is provided with an insertion hole through which the mounting bolt is inserted, and
the cover plate is put in a predefined assembled state by arranging the cover plate on the mounting portions such that the mounting bolts are inserted into the insertion holes.

6. The vehicle oil pan guard according to claim 5 , wherein
the predefined assembled state is a state in which the cover plate and the guard plate are substantially parallel to each other and overlapped with each other in a boundary portion.

7. The vehicle oil pan guard according to claim 1 , wherein
the vehicle oil pan guard is disposed on a front-and-rear-wheel drive vehicle including a longitudinally-mounted transmission and a transfer disposed on the output side of the transmission to distribute a drive force to front and rear wheels, and
the vehicle oil pan guard is disposed at a position under the oil pan for protecting the oil pan which is disposed on a lower portion of the transmission.

8. A vehicle power transmission device comprising
the vehicle oil pan guard according to claim 1 , a longitudinally-mounted transmission, and a transfer to receive a drive force from output of the transmission and to distribute the drive force to front rear wheels, wherein,
the oil pan is disposed on a lower portion of the transmission, and
the vehicle oil pan guard is disposed at a position under the oil pan such that the vehicle oil pan guard protects the oil pan.
