Abstract

The suspension member includes: a rear cross member that extends along the vehicle width direction, and that includes a left and right pair of sub side rails that integrally extend from respective vehicle width direction end portions of the rear cross member toward the vehicle body front side; and a left and right pair of side rails that extend along the extension direction of the sub side rails, that each include a bent portion protruding toward the vehicle body lower side at an extension direction intermediate portion of the side rail, wherein the upper side of an end portion further toward a vehicle body rear side than the bent portion is covered by, and joined to, the respective sub side rail, and the lower side of the end portion further toward the vehicle body rear side than the bent portion is in an exposed state.

Description

technical field [0001] The present invention relates to a suspension member of a vehicle. Background technique [0002] Conventionally, there is known a suspension member in which left and right rear joints and a rear beam are integrally formed by die casting, left and right front joints are formed by die casting, and a front joint is formed by extrusion molding. The upper beam and the left and right longitudinal beams (for example, refer to Japanese Patent Application Laid-Open No. 2005-289131). [0003] However, in the event of a frontal collision of the vehicle, etc., the left and right side members (side frames) of the suspension member are bent and deformed into a downward convex shape due to the load input from the front side of the vehicle body, and the structure that can effectively absorb the load still remains There is room for improvement. Contents of the invention [0004] The present invention provides a suspension member capable of effectively absorbing a l...
