きは手直し工場５で補修してからモータプール２に搬入
して保管し、異音が無いときはそのままモータプール２
に搬入して保管する。According to the structure of this embodiment, the automobile A shipped from the assembly plant 1 to the motor pool 2 travels on the artificial rough road 4 by itself. At this time, the driver listens to the presence or absence of abnormal noises such as rattling and clicking, and checks. If there is abnormal noise, repair it at the repair factory 5 and then load it into the motor pool 2 for storage.
Bring in and store.
