Abstract
A friction welding apparatus includes a first holder for holding a first work piece, a second holder for holding a second work piece, a thrust mechanism and a shaft. The thrust mechanism moves the second holder toward or away from the first holder. The shaft is connected to the first holder and the second holder for receiving thrust caused by the thrust mechanism. The shaft has a tie rod and an externally threaded member which is coaxially connected to the tie rod so that the externally threaded member is rotatable on an axis thereof. The thrust mechanism has the externally threaded member, an internally threaded member and a thrust motor. The internally threaded member is provided in either one of the first holder and the second holder and engaged with the externally threaded member. The thrust motor rotates the externally threaded member relative to the internally threaded member.
