1. A valve automation mechanism that is attached to a predetermined valve having a valve box, which is attached to a valve rod and a handle, and controls a flow of a fluid inside the valve box by rotating the handle and moving the handle and the valve rod forward and backward along a longitudinal direction of the valve rod, and is capable of automatically rotating the handle, the valve automation mechanism comprising:
a handle holding portion attached to the handle;
a handle rotating gear located between the valve box and the handle in the longitudinal direction of the valve rod, attached to the handle holding portion, and configured to rotate integrally with the handle;
a gear supporting portion comprising:
a substantially tubular body that is substantially parallel to a plane defined by the handle and is located between the valve rod and the handle rotating gear and
a through hole into which the valve rod is inserted;
a valve attaching portion located between the valve box and the handle in the longitudinal direction of the valve rod, connected to the gear supporting portion, and attached to the predetermined valve such that rotation around a position of the valve rod is restricted;
a drive mechanism located between the valve box and the handle in the longitudinal direction of the valve rod, attached to the valve attaching portion, and having a motor and a speed reducer; and
a drive mechanism gear attached to the speed reducer, configured to be rotatable by a driving force of the motor, and transmitting power by engagement of the handle rotating gear and the drive mechanism gear.
