Abstract
Almost all of the troubles with transmission systems of railway vehicles are brought about by various phenomena occurred at the time of starting. The author probed into the cause of these troubles with the driving axle of diesel car of the KIHA type and measured strsses in parts of quill drive.
The results are arranged to clarify the cause and state of troubles. This will furnish some clues to locate the cause from the state of trouble and valuable data for future planning.
