STRUCTURE FOR MOUNTING ELECTRONIC DEVICE MODULE ON VEHICLE

An electrical component module 1 is installed in a front (rear) section of a vehicle, and connected with a battery unit storing electricity for driving the vehicle. The electrical component module 1 is supported by a vehicle body structure member (cross-member) 2 extending in a lateral direction of the vehicle. The cross-member 2 is closer to a passenger compartment than the electrical component module 1, and doesn't overlap with the electrical component module 1 when viewed along any horizontal direction perpendicular to a vertical direction of the vehicle. Between the cross-member 2 and the electrical component module 1, provided is a release mechanism 4 for releasing the support of the electrical component module 1 by the cross-member 2 when receiving an impact from an opposite side to the passenger compartment. Since the cross-member 2 is vertically offset to the electrical component module 1, the electrical component module 1 whose support has been released never collides against the cross-member 2 even while being displaced due to the impact.
