Abstract
PURPOSE: To reduce the number of manufacturing steps and prevent flexing by forming a damper blade with a groove extending along the axis of its rotation by using a press mold or the like and providing a cylindrical shaft capable of engagement with a drive shaft and a bearing at the opposite ends.
CONSTITUTION: A blade 1a made of a steel plate is formed with a groove 7 extending along the axis of its rotation with a press mold or the like. The groove 7 suitably has a shape that fits on a cylindrical shaft. The cylindrical shaft 5 is secured by welding, and its length is substantially the same as the length of the blade 1a. One end of the cylindrical shaft 5 is fitted on a bearing 6a secured to a frame 9. A drive shaft 3a is fitted on and firmly secured to the cylindrical shaft 5 for transmitting the torque of the drive shaft 3a to the cylindrical shaft 5.
