Abstract

Official abstract text for this publication.

A rack manufacturing apparatus and a rack manufacturing method are provided. The rack manufacturing apparatus includes a first support portion configured to support a hollow or solid first bar on which first rack teeth are formed, a second support portion configured to support a hollow or solid second bar such that an axial center line of the second bar is aligned with an axial center line of the first bar, a base configured to cause the second support portion to approach the first support portion, and a rotary driving portion configured to rotate the second support portion about the axial center line of the second support portion relative to the first support portion so as to join an end portion of the first bar and an end portion of the second bar by a friction pressure welding.
