The present disclosure provides a waterproof unit and a wire harness capable of suppressing a decrease in waterproofness. The waterproof unit (31) has: a tubular waterproof member (50) fitted to a through-hole (200X) of a vehicle body panel (200) provided between the outside of the vehicle interior, which is a waterproof region, and the inside of the vehicle interior, which is a non-waterproof region; and a tubular waterproof member (90) provided in the vehicle interior so as to be separated from the waterproof member (50). The waterproof unit (31) is provided with a corrugated pipe (100) which is arranged between the waterproof member (50) and the waterproof member (90) and is connected with the waterproof member (50) and the waterproof member (90). The flexural rigidity of the bellows (100) is higher than the flexural rigidity of the waterproof member (50).
本公开提供能抑制防水性降低的防水单元及线束。防水单元(31)具有:筒状的防水构件(50),装配于车身面板(200)的贯穿孔(200X),车身面板(200)设置于作为防水区域的车厢外和作为非防水区域的车厢内之间;和筒状的防水构件(90),在车厢内与防水构件(50)分离地设置。防水单元(31)具有波纹管(100),波纹管(100)设置于防水构件(50)与防水构件(90)之间,与防水构件(50)和防水构件(90)连结。波纹管(100)的弯曲刚性比防水构件(50)的弯曲刚性形成得高。
