PURPOSE: A coupler for the longitudinal axis having a vibration releasing and bending protection function is provided to release the vibration of revolving longitudinal axis, extend the lifespan by protecting the bending of a longitudinal axis, proceed the task by tools smoothly. CONSTITUTION: A coupler(100) for the longitudinal axis having a vibration releasing and bending protection function comprises a supporting member(20), a first fixing ring(110), a second fixing ring(120), a shaft connector(130), a rubber bushing(140), a fixing bolt(150), and a nut(160). The supporting member forms the longitudinal axis having interval on the circumference by attaching a support piece(22) along the longitudinal direction. The first fixing ring and second fixing ring are attached to the supporting member arranged along the longitudinal direction. The shaft coupling is installed between the first fixing ring, a second fixing ring and comprises a boss(133). The boss is connected to a rotary shaft of the driving motor. A rubber bushing is inserted in the coupling hole of the shaft coupling and installed and absorbs the vibration from the driving motor and supporting member. The fixing bolt penetrates the shaft coupling through the first fixing ring and second fixing ring through the rubber bushing. The nut is coupled with the fixing bolt.
