2. According to Gap evidence No. 2 (construction machine registration certificate), although the construction machine in this case is registered as owned by the defendant, the person who requested the plaintiff to repair and repair the construction machine in this case as stated at the first date of pleading is not the defendant but F, and the plaintiff was not aware of the defendant at all, it is insufficient to recognize that the above facts of recognition and the evidence submitted by the plaintiff alone requested the plaintiff to repair and repair the construction machine in this case, and there is no other evidence to acknowledge otherwise.
