The utility model relates to a fastener of refrigerating module (5) on the motor vehicle, include: setting deformation element (3) of both sides between frame (1) and anterior bumper (2), a supporting rack (4) for keeping refrigerating module (5), and be used for the protection mechanism of the absorbed energy of refrigerating module (5). Refrigerating module (5) should obtain best protection at least in slight collision to it does not as far as possible receive the damage, and fastener's structure should be simply and the assembly should be uncomplicated in addition. According to the utility model discloses, this point can be realized through following mode: supporting rack (4) of refrigerating module (5) set up and fix on deformation element between two deformation element (3) to the ground supporting can be shifted on deformation element at least in supporting rack (4) relative deformation element (3) along the vertical orientation of vehicle.
