PURPOSE:To enable the right angle degree of the shaft end on the load side to the end face on the load side, to be easily shown at a high precision, by providing the both ends of the shaft with center holes, and by processing the end face of a bearing bracket on the load side based on the center holes. CONSTITUTION:Center holes 1b, 1c having concentricity with the outer diameter of a shaft 1 are bored through the both ends of the shaft 1. After a bearing bracket 2 on the load side and a bearing bracket 7 on the counter-load side are fitted at both ends of the shaft 1, the end face 2a on the load side of the bearing bracket 2 on the load side is processed on the basis of the center holes 1b, 1c. As the result, the right angle degree of a shaft center to the end face 2a on the load side can be shown at a high precision, and the process can be simplified.
