PURPOSE: A vent piece used in a tire curing mold is provided to rapidly and easily carry out an installing work of the vent piece to the tire curing mold and an exchanging work of the vent piece by improving a structure of the vent piece. CONSTITUTION: An installing hole, to which a vent piece(2) is inserted, is formed in a tire curing mold. A perforation hole(20) is formed at a center of the vent piece(2). The perforation hole(20) has a size adapted for allowing air to be discharged therethrough and preventing rubber of a green tire from passing therethrough. A diameter of an upper portion of the installing hole is smaller than a diameter of a lower portion of the installing hole, such that a locking protrusion is formed at a center of the installing hole. A plurality of elastic protrusions(21) are formed at a lower portion of the vent piece(2). A locking section(22) is formed at an upper peripheral portion of the vent piece(2).
