Abstract
A vibration absorbing bearing supports an armature shaft and a blower motor for vehicles. The vibration absorbing bearing may include a longitudinal groove which is formed on the inner circumference of the bearing in such a way as to extend in a longitudinal direction and hold a lubricant therein. The blower motor for vehicles may include a main body, a stator installed in the main body, an armature assembly installed in the main body and having an armature shaft, and the vibration absorbing bearing. Such a construction improves the durability of components and achieves the joining of the components and the absorption of vibration, thus efficiently isolating cogging noise.
