The present invention relates to a power transmission member of an electric power steering apparatus, which connects a drive shaft and a driven shaft to be coaxial and transmits power. The present invention comprises: a first boss coupled to one side of the drive shaft and the driven shaft and having a first cylindrical accommodation portion in the center thereof; a second boss coupled to the other side of the drive shaft and the driven shaft and having a second cylindrical accommodation portion in the center thereof; and an axial damper having one end and the other end, respectively, inserted into the first and the second accommodation portion, and elastically changing in an axial direction. Accordingly, the present invention can remove noises caused by clearance between an inner rotor and an outer rotor compared to an existing power transmission member, and prevent noises due to collisions and vibrations caused in the part where the drive shaft and the driven shaft are coupled, when the power is transmitted.
