A combustion air blower assembly for a furnace includes a casing, a blower in said casing and a motor for driving said blower secured to said casing. This invention provides unique mounting means for securing the motor in close proximity to the casing, while allowing motor flexure in a direction radial to the axis of the motor to dissipate torsional vibration energy and maintaining the structural integrity of the motor in the axis thereof. The mounting means comprise a plurality of generally J-shaped isolation springs having a loop at each end. One loop of each isolation spring is secured to the casing and the other loop is secured to a bracket on the motor. Each isolation spring is generally flat and extends generally perpendicular from the wall of the casing to which the motor is secured.
