The cross member has both ends fixed to side framework structures of the vehicle body. The cross member includes a base frame extending in the width direction and reinforcing frame parts formed in integral with the base frame to cover the circumference of the base frame within its limited ranges in the width direction of the vehicle body. The base frame and the reinforcing frame parts are made from the same resinous material or plural resinous materials belonging to engineering plastic system.
SUMMARY In the above situation, it is an object of the present invention to provide a cross member having high strength in the member's part where high strength is required and also having superior recycling efficiency and a manufacturing method of such a cross member.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a cross member in prior art;
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to accompanying drawings showing the details of a cross member and its manufacturing method, embodiments of the present invention will be described below.
1st. Embodiment As shown in FIGS. 3 and 4, a cross member 1 includes a base frame 2, a first reinforcing frame part 3 and a second reinforcing frame part 4 all formed in one body. The base frame 2 is arranged on the backside of an instrument panel (not shown) of a vehicle so as to extend in the width direction of the vehicle. Within a range of a driver's seat in the width direction of the base frame 2, the first reinforcing frame part 3 is arranged so as to cover the circumference of the base frame 2. On the opposite side of the first reinforcing frame part 3, the second reinforcing frame part 4 is arranged so as to cover the circumference of the base frame 2 at its end.
2nd. Embodiment As shown in FIG. 7, a cross member 110 of the second embodiment is formed by, in detail, a steering member that is arranged between the lower parts of front pillars in front of a vehicle cabin to extent in the width direction of the vehicle, for supporting the steering column and the instrument panel. The cross member 110 includes a base frame 111 spreading over the whole width of the vehicle cabin in the width direction of the vehicle and a reinforcing frame part 112 that reinforces the base frame's part extending from the lower part of the front pillar (driver's seat side) to the vicinity of the steering column to support the steering column. As shown in FIG. 8, which is a sectional view taken along a line 8-8 of FIG. 7, both of the base frame 111 and the reinforcing frame part 112 are shaped to have oval sections. In arrangement, the base frame 111 is inserted inside the reinforcing frame part 112 to mutual fixation.
3rd. Embodiment Next, the third embodiment of the present invention will hereafter be described. Note, in the third embodiment, elements identical to those elements in the second embodiment will be indicated with the same reference numerals and, therefore, their overlapping descriptions are omitted.
