Abstract
Abstract A processing jig is provided for deforming an object to be processed that is long in one direction into a complicated shape and processing the object with accuracy. The jig comprises: a main body to be fixed to the processing apparatus; a retainer that is long in one direction for retaining a bar as the object long in one direction; four couplers for coupling the retainer and the main body to each other; three load application sections, coupled to the retainer, to which a load is applied for deforming the retainer; and arms for coupling the load application sections to the retainer. The retainer takes a shape of a narrow and long beam that is bent with an application of external force. The two load application sections on both ends each have three degrees of freedom in two directions orthogonal to each other and a direction of rotation, for example. The load application section in the middle has one degree of freedom in the vertical direction only.
