PROBLEM TO BE SOLVED: To provide a vent plug for a storage battery capable of being integrally resin-molded, and also highly retaining a liquid overflow-proof effect as well as a function of a splash-proof body. SOLUTION: While the vent plug has a flange part 3, a screw part 5, and a cylinder part 9 having the splash-proof body 7 inside integrally resin-molded, the cylinder part 9 including the splash-proof body 7 is divided into two portions. Respective end parts of the halved cylinder portions 9A, 9B are hinge-connected to the screw part 5 through a thin part with their cut faces in a state opposed to each other in free expansion, and a locking member 15 is provided to lock the respective cylinder portions to each other.
