Setting shaft unit producing method for intake manifold of internal combustion engine, involves attaching bearing block at setting shaft and moving bearing block in axial direction along setting shaft at respective predetermined positions

摘要

The method involves producing a setting shaft (10) that has a predetermined external diameter in a predetermined position and another predetermined external diameter in another predetermined position, where the latter predetermined external diameter is smaller than the former predetermined external diameter. A bearing block (14) is attached at the setting shaft at the former predetermined position and is moved in an axial direction (20) along the setting shaft at the latter predetermined position, where the bearing block is arranged at the setting shaft in a rotatable manner.
