The utility model relates to a drainage hole plug, which ensures good drainage and restrains rain water from outside to inside of the vehicle even if the outburst towards the outside of the vehicle is reduced under the installation condition of the plate. The drainage hole plug has a protrusion part and a barrel-shaped part, which is installed into a barrel-shaped part and inserted into the installation hole of the side panel of the car body, so that the liquid such as rainwater entering the car can flow into the barrel-shaped part, and the liquid flowing into the barrel can flow out from the drainage hole arranged at the protrusion part to the outside of the car. It is characterized by that the protrusion part is composed of a roughly disc-shaped flange (1) and protrudes on the inner side of the flange. The outlet is provided with a cylindrical part (2), and has a drainage hole (14). The cylindrical part (2) has: a clamping foot part (25), which is arranged around the cylindrical part, and is clamped or detached from the installation hole (4a); and a barrier wall (24), which is set in the following state: positioned directly above the drainage hole (14), is larger than the horizontal section of the drainage hole, and connects the cylinder with the drainage hole.
