PROBLEM TO BE SOLVED: To provide a device for controlling deformation of a vehicle body frame capable of always properly deforming a vehicle body frame in a plurality of different collision forms. SOLUTION: A piezoelectric element actuator 32 capable of generating loads along a vehicle body frame 11 is installed on inner angle sides of bending parts 21, 22 of a vehicle body frame 11 including the bending parts 21, 22, and a control means for controlling loads of the piezoelectric element actuator 32 is provided. When loads in an extension direction is generated to the piezoelectric element actuator 32, the actuator holds on, so as to restrain folding of the bending part 21. When the loads are not generated to the piezoelectric element actuator 32, folding can be generated. COPYRIGHT: (C)2005,JPO&NCIPI
