Abstract
A center member structure for use in a motor vehicle is disclosed which is designed to support thereon an engine unit. The center member structure comprises two pipe members arranged side by side and having first portions which extend in parallel and second portions which gradually separate from each other with increase of the distance from generally middle portions of the pipe members; and reinforcing plates welded to given portions of the pipe members to tightly combine the pipe members into a robust unit.

A center member structure for use in a motor vehicle to support thereon an engine unit, comprising:
- two pipe members arranged side by side, said pipe members having first portions which extend in parallel and second portions which gradually separate from each other with increase of the distance from generally middle portions of the pipe members;
- and
- two longitudinally extending reinforcing plates welded to given portions of said pipe members to tightly combine the pipe members into a rubust unit.
A center member structure for use in a motor vehicle to support thereon an engine unit, comprising;
- two steel pipe members arranged side by side, said pipe members having first portions which extend in parallel and second portions which gradually separate from each other with increase of the distance from generally middle portions of the pipe members;
- and
- reinforcing plates welded to predetermined portions of said pipe members to tightly combine the pipe members into a robust unit;
- said reinforcing plates comprising:
- an upper reinforcing cover plate covering first given portions of said pipe members and welded to the same and a lower reinforcing cover plate covering second given portions of said pipe members and welded to the same, said upper and lower reinforcing cover plates being arranged so that the pipe members are therebetween.
A center member structure for use in a motor vehicle to support thereon an engine unit, comprising:
- two pipe members arranged side by side, said pipe members having first portions which extend in parallel and second portions which gradually separate from each other with increase of the distance from generally middle portions of the pipe members;
- and
- reinforcing plates welded to given portions of said pipe members to tightly combine the pipe members into a robust unit, each pipe member being formed with respective openings at its first and second ends, the openings being adapted to receive therethrough bolts for bolting said pipe member to the motor vehicle.

- two pipe members arranged side by side, said pipe members having first portions which extend in parallel and second portions which gradually separate from each other with increase of the distance from generally middle portions of the pipe members;
- and
- reinforcing plates welded to given portions of said pipe members to tightly combine the pipe members into a robust unit,
- wherein said first portions have a cross section taken by an imaginary plane which perpendicularly crosses the longitudinal axes of said first portions, said cross section satisfying the following inequality:
- A/2.gtoreq.B
- wherein:
- A is the distance between outermost and innermost portions of one of said first portions, through which a horizontal line passes, and
- B is the distance between respective facing portions of said first portions.
