Conventionally, various things have been proposed. As a specific example of this conventional method, first, as disclosed in Japanese Utility Model Laid-Open No. 49-35022, an output shaft or an intermediate shaft of an actuator is protruded to the outside of a casing, and this protruding portion is fixed to a predetermined position. 2. Description of the Related Art There is a known type in which a stem of a valve is manually operated by being rotated using a tool such as a spanner. In Japanese Patent Publication No. 49-2214, the lower end of the output shaft protruding from the lower part of the actuator and the upper end of the stem protruding from the upper part of the valve are connected by a connector. There has been proposed an apparatus that opens and closes a valve by manually operating a stem of the valve by rotating the stem.

の欠点があった。However, the former structure requires a sealing member for sealing the protruding portion in order to maintain the hermeticity of the portion where the protruding portion protrudes from the casing. You need tools,
Further, the latter structure for rotating the connector has disadvantages in that the connector is disposed below and outside the actuator, so that the size of the connector cannot be satisfied and the demand for compactness cannot be satisfied.

た。Further, in the above-mentioned conventional structure, since the operating force at the time of manual operation is increased, the operating force is reduced by providing a clutch mechanism in the actuator to disconnect the gears. Due to the mechanism, the structure is complicated, and in any case, not only is a tool such as a predetermined spanner required, but also a restriction on the installation location of a valve for turning the spanner is required, A space for turning a tool such as a spanner must be secured in the actuator itself, and therefore, there have been various problems such as inconvenience in rotating the spanner or the like in a narrow place.

The operability is improved by reducing the operating force at the time of manual operation, and the product can be compactly manufactured without providing a special manual operation portion. It is another object of the present invention to provide a new and useful actuator which does not require a rotary operation tool such as a spanner.
