ｅが取着されていた。 Generally, a floor panel of an automobile has a stepped portion formed in the vehicle width direction, and this stepped portion has a cross-sectional shape, as disclosed in Japanese Utility Model Application Publication No. 55-4907, which was previously filed by the present applicant. It is reinforced by attaching a shaped cross member. As shown in the conventional example in Fig. 1, a bracket d, which has a cross-sectional shape and is folded back on both the left and right sides, is attached to the bent part b of the cross member a by spot welding (X marks indicate welding points). A side frame e was attached to the back of the rising surface c.

である。 In the present invention, the vertical part of the bracket for mounting auxiliary parts provided on the cross member reaches the attachment part between the cross member and the side frame, and is installed on both the left and right sides of the bracket from the upper edge of the vertical part. By forming a triangular reinforcing surface section with an edge that reaches the tip edge of the bottom section, the torsional rigidity of the side frame is improved, and the collision load in the event of a vehicle collision is smoothly transmitted to the side frame, preventing deformation of the cross member, etc. The purpose is to prevent

４に支持される。 In the figure, reference numeral 1 denotes a floor pan, which has a high floor 11 and a low floor 12 separated by a step 10 in the vehicle width direction. Reference numeral 2 denotes a cross member having a cross-sectional shape, and the cross member 2 is connected to the stepped portion 10.
It is installed in the width direction of the vehicle. Reference numeral 3 denotes a side frame having a substantially shaped cross section, which supports the high floor 11 and has one end attached to the rising surface 20 of the cross member 2. 4 is a bracket for mounting auxiliary parts, and as shown in Fig. 3, the vertical part 4
A triangular reinforcing surface portion 42 is integrally formed with a cross-sectional shape of 0 and the bottom portion 41, and has edges extending from the upper edge 40f of the vertical portion 40 to the tip edge 41f of the bottom portion 41 on both left and right sides. ing. Bottom part 4
1 is provided with a hole for inserting a fixing fitting such as a bolt, and a nut 43 is welded thereto, and one end of the rear suspension is supported by the bracket 4 via the fixing fitting.

に、伝達させることができる。 Further, a collar g is connected to the edges of the vertical surface portion 40, the left and right reinforcing surface portions 42, and the bottom surface portion 41. As shown in FIG. 4, the bracket 4 is attached to the acute angle side of the bent portion 21 of the cross member 2, and the upper end of the vertical portion 40 is attached to the lower end of the side frame 3 via the cross member 2. The bracket 4, cross member 2, and side frame 3 are joined by welding at the same position as the attachment piece 30. With this structure, when a vehicle collides, the collision load can be transmitted as shown by the arrow in the figure.

奏するものである。 Therefore, according to the present invention, the collision load at the time of a collision can be smoothly transmitted to the side frame by the bracket provided on the cross member and supporting one end of the rear suspension. Furthermore, since the bracket, cross member, and side frame are integrally connected by welding, the torsional rigidity of the side frame is improved, and the rear suspension can be firmly supported, which has excellent practical effects.
