PROBLEM TO BE SOLVED: To provide a bending hole correction drilling method for achieving remarkable correction effect of bending hole correction.;SOLUTION: In this multispindle drilling machine, each of a first excavation shaft 61 and a second excavation shaft 62 on both sides among three excavation shafts has upper basic part shafts 61A, 63A and lower main body shafts 61B, 63B, a connection body 20 for connecting the excavation shafts to keep them in parallel is provided in a lower part of each excavation shaft, each of the first and second excavation shafts 61, 63 is connected with the basic part shafts 61A, 63A in such a way that the main body shafts 61B, 63B can rotate and move in the axial direction by traveling means 12A, 12B, 12C, 12D, and each excavation shaft has continuously provided parts 30, 30, 30 bendable in at least one regular axial direction in the vertical direction between a connection part and the connection body 20. When the main body shaft 61B of the first excavation shaft 61 is positioned relatively below the main body shaft 63B of the second excavation shaft 63, a part below each continuously provided part 30 is bent onto a second excavation shaft 63 side integrally with the connection body 20.;COPYRIGHT: (C)2008,JPO&INPIT
