The present invention relates to a grease injection nipple coupled to a grease pipe such that the same can function as an opening/closing valve with regard to the corresponding grease pipe, the grease injection nipple being pushed against a nipple of a grease supply target and coupled thereto or separated therefrom. The grease injection nipple according to the present invention comprises a push body, a check valve, a nipple coupling portion, and a valve activation portion. The valve activation portion may operate such that, when the push body makes a primary movement in the forward direction, the check valve is opened and, when the push body makes a secondary movement in the forward direction after external force for the primary movement of the push body is released, the check valve is closed.
