PURPOSE:To prevent the deformation of a bracket for a rotary electric machine by forming the joint of a divided bracket arms by full welding at the lower part from a neutral shaft and by shallow groove welding at the upper part. CONSTITUTION:A bracket body 1 and bracket arm 2 which extends externally from the outer periphery of a bracket body 1 are divided and manufactured in advance, and the divided parts 5 in an installing site are bonded by welding. In this case, the part, to which a tensile stress is acted from the neutral shaft of the divided part is bonded by full welding, and the part, to which a compression stress is applied from the neutral shaft, is bonded by shallow groove welding. Then, even if the bracket is bonded by the welding, problems of strength and deflection can be prevented from being induced. |
