摘要： A vehicle lifting jack having a jack shaft, a load lifting assembly supported on and operably associated therewith for vertical movement therealong, and an improved load engaging member pivotably affixed to the load lifting assembly. The load engaging member includes a stabilizing torque arm having a roller at the extending end thereof for bearing engagement of the shaft to isolate torque created during operation to the load engaging member and direct such torque to the shaft, thereby preventing rotation of the load lifting assembly with respect to the shaft. To prevent damage to the vehicle bumper during operation, the load engaging member also includes a cantilevered portion, a vehicle frame engaging element extending upwardly therefrom for liftingly engaging the vehicle frame, and a bumper engaging element for cushioned abutting contact with the vehicle bumper during operation.
