PROBLEM TO BE SOLVED: To provide an adapter for an electric-operated valve capable of preventing the leakage of the lubricating oil from the side of the electric-operated valve while the spring compression mechanism to the electric-operated valve and the warm movement quantity measuring means can be installed when inspecting the electric-operated valve. SOLUTION: While the intermediate body to transfer the compression power by the above spring compression mechanism to a spring cartridge is held on an adapter for the electric-operated valve that can install each of the spring compression mechanism and the worm movement quantity measuring means to a valve drive part, the intermediate body has a weir body to prevent the leakage of the lubricating oil from the side of the above valve drive part when attaching or detaching the above spring compression mechanism and the above worm movement quantity measuring means. The inspection cost of the electric-operated valve can be reduced, because the above spring compression mechanism and the worm movement quantity measuring means can be shared between the electric-operated valve according to such constitution. Also, the lubricating oil filled up in the above spring cartridge side is prevented from leaking to the outside through the above adapter by the above weir body. COPYRIGHT: (C)2007,JPO&INPIT
