PROBLEM TO BE SOLVED: To provide a vehicle cross member for securing well-balanced rigidity and strength without increasing the weight of a vehicle body by efficiently dispersing a load. SOLUTION: The vehicle cross member 9b is fixed to a pair of right and left side rails 8 extending in a vehicle longitudinal direction to form a ladder type chassis frame with the side rails 8 connected to each other in a vehicle cross direction. A first member 1 is fixed to the inner face of a web 8a of one of the pair of right and left side rails 8, and a second member 2 is fixed to the inner face of a web 8a of the other. a clutch deice 3 is mounted between the first member 1 and the second member 2. The torque transmission property of the clutch device 3 is set so that, when torsion torque of a predetermined value or greater works on the pair of right and left side rails 8, the clutch device 3 slips in the peripheral direction of the cross member 9b to release the torsion torque.
