PROBLEM TO BE SOLVED: To provide a vehicle body frame buckling control device capable of always properly buckling a vehicle body frame in a plurality of different collision forms. SOLUTION: A piezoelectric element actuator 25 capable of generating loads along an extension direction of a vehicle body frame 11 is installed to a vehicle body frame 11, and a control means for controlling loads of the piezoelectric element actuator 25 is provided. When lengthwise loads are generated to the piezoelectric element actuator 25, the actuator holds on and rigidity of the vehicle body frame 11 increases, so that it becomes safe against buckling. Contrarily, when the lengthwise loads are generated or not generated to the piezoelectric element actuator 25, rigidity of the vehicle body frame 11 becomes lower than the above-mentioned case, so as to promote buckling.
