駆動装置。 A board attached to the valve housing and a base plate on which the motor is installed are arranged in parallel, and a reduction gear train for transmitting the rotational force of the motor to the output gear is installed between the base plate and the base plate. They are mounted and arranged on several shafts held perpendicular to the plate, and are attached to any one of the intermediate shafts of the reduction gear train with an intermediate idler gear forming a part of the reduction gear train and for manual operation. The handle shafts are fitted together so as to be slidable in the axial direction and rotatable around the shafts, and a torque transmission engagement protrusion is projected on the outer periphery of the intermediate shaft between the intermediate idler gear and the handle shaft. At the same time, engagement recesses that are engaged with and disengaged from the engagement protrusions are cut in the axial direction on each opposing end surface of the intermediate idler gear and the handle shaft, and an automatic return spring that biases and holds the handle shaft in an axially displaced position where it engages with the engagement protrusion, and biases and holds the handle shaft in an axially displaced position where its engagement recess separates from the engagement protrusion; An electric valve drive device with an automatic manual switching mechanism.
