Abstract

There is provided a maintenance cover member including: a cover body for closing an opening of a power train of a vehicle; and a vibration suppressing member attached to a surface of the cover body. There is also provided a maintenance cover member including: a cover body for closing an opening of a power train of a vehicle; and a plurality of vibration suppressing members attached to a surface of the cover body. Adjacent vibration suppressing members are disposed spaced apart from each other.

First claim

What is claimed is:

1. A maintenance cover member used to close an opening of a power train of a vehicle, the maintenance cover member comprising:
a cover body for closing the opening disposed between an oil pan and a transmission of the vehicle; and
a vibration suppressing member attached to a surface of the cover body,
wherein the cover body has a first edge portion fixed to the oil pan and a second edge portion opposite to the first edge portion and fixed to the transmission, and the cover body is fixed to a peripheral edge portion of the opening using fastening members such that one fixing position and a plurality of fixing positions opposite to the one fixing position are arranged on the first edge portion and the second edge portion, and
wherein the vibration suppressing member is a block-shaped rubber member and is disposed on imaginary lines connecting the one fixing position and the plurality of fixing positions.

2. The maintenance cover member according to claim 1 , wherein the vibration suppressing member is vulcanized and bonded to the surface of the cover body.

3. The maintenance cover member according to claim 1 , wherein the vibration suppressing member comprises a plurality of vibration suppressing members, and
wherein adjacent vibration suppressing members are disposed spaced apart from each other, and each of the vibration suppressing members is disposed on one of the imaginary lines that connects the one fixing position and one of the plurality of fixing positions.

4. The maintenance cover member according to claim 1 , wherein the vibration suppressing member is disposed on midpoints of the imaginary lines.

5. The maintenance cover member according to claim 1 , wherein the fastening members are bolts inserted through bolt holes formed in the first edge portion and the second edge portion.

6. A maintenance cover member used to close an opening of a power train of a vehicle, the maintenance cover member comprising:
a cover body for closing the opening disposed between an oil pan and a transmission of the vehicle; and
a plurality of vibration suppressing members attached to a surface of the cover body,
wherein adjacent vibration suppressing members are disposed spaced apart from each other,
wherein the cover body has a first edge portion fixed to the oil pan and a second edge portion opposite to the first edge portion and fixed to the transmission, and the cover body is fixed to a peripheral edge portion of the opening using fastening members such that one fixing position and a plurality of fixing positions opposite to the one fixing position are arranged on the first edge portion and the second edge portion, and
wherein each of the vibration suppressing members is disposed on an imaginary line connecting the one fixing position and one of the plurality of fixing positions.

7. The maintenance cover member according to claim 6 , wherein each of the vibration suppressing members is a block-shaped rubber member vulcanized and bonded to the surface of the cover body.

8. The maintenance cover member according to claim 6 , wherein the plurality of vibration suppressing members are disposed on midpoints of the imaginary lines.

9. The maintenance cover member according to claim 6 , wherein the fastening members are bolts inserted through bolt holes formed in the first edge portion and the second edge portion.
