An operating hinge for a seat and seat lid of a toilet bowl, simply constructed and capable of controlling the angular moment of the seat and lid to softly stop them in place at their respective predetermined ends of pivoting stroke, provided. The operating hinge comprises a hinge case to be installed to a body of a toilet bowl, a shaft provided rotatably within the hinge case, a stationary cam secured inside the hinge case and having formed therein a central hole through which the rotating shaft is axially penetrated, a cam provided inside the hinge case in a vis-a-vis relationship with the stationary cam and having formed therein a central hole through which the rotating shaft is axially penetrated, to be slidable on, and rotatable with, the rotating shaft, and a resilient member for urging the rotatable sliding cam toward the stationary cam; further comprising, to more positively control the rotation of the rotating shaft, a rubber ring fitted on the rotating shaft to abut the inner wall of the hinge case, and a viscous oil applied between the periphery of the rubber ring and the hinge case inner wall the rubber ring abuts.
