To provide a plug which has adhesion to a rust inhibitor and further has improved processability.SOLUTION: The plug according to the present disclosure is a rubber plug for closing a through hole of a vehicle and is formed from a composition for rubber production containing an ethylene-propylene-diene polymer, a chloroprene polymer, and an oil. The composition for rubber production contains 40 pts.wt. or more of the oil based on 100 pts.wt. of the total of the ethylene-propylene-diene polymer and the chloroprene polymer.SELECTED DRAWING: Figure 1
