Abstract:
1. An apparatus for preventing deformation of a plastic battery pack case for a vehicle, the apparatus comprising: a base having a case insertion space; a fixing portion for fixing a battery pack case inserted into the case insertion space; and a reverse deformation producing portion inserted into the battery pack case and pressing inside of the case outwardly so as to prevent the case from being deformed inwardly by contraction when it is cooled after compression molding, wherein the reverse deformation producing portion comprises: a reverse deformation applying block disposed to be in contact with the inside of the case to outwardly deform the side of the case; a ratchet handle for generation a rotational force; and a bolt portion and nut portion for converting the rotational force of the ratchet handle into a linear movement force to press the side of the case and transmitting the linear movement force to the reverse deformation applying block.
