Claims (1)

[Claims for Utility Model Registration] (1) In a valve drive device in which a power section displaces a valve via a transmission shaft, the transmission shaft is divided into a driving shaft section and a driven shaft section, and the transmission shaft is substantially perpendicular to the transmission shaft. A manual handle with an input shaft is provided,
A valve driving device further comprising a transmission switching mechanism that selectively transmits the rotation of the drive shaft portion and the input shaft portion to the driven shaft portion. (2) The transmission switching mechanism is provided with a clutch member on the drive shaft portion that is rotationally restricted and slidable in the axial direction, and is connected to the driven shaft portion by moving forward and disconnecting by moving backward. between the input shaft and the clutch member,
A clutch operating mechanism is provided in which the input shaft advances to open and disengage the clutch member, and retreats to connect the clutch member, and further, the input shaft advances to engage and retreat, and is provided between the input shaft and the driven shaft portion. 2. The valve driving device according to claim 1, further comprising a transmission gear mechanism for disengaging the valve. (3) The valve driving device according to claim 1, wherein the clutch operating mechanism has an end portion of the clutch member and an end portion of the input shaft formed into a conical shape, and are disposed so that their circumferential surfaces face each other. (4) The valve driving device according to claim 1, wherein the transmission gear mechanism is provided with bevel gears for changing the direction of rotation transmission at the end of the input shaft and the end of the driven shaft, respectively. (5) In a drain plug device, a power unit for transmitting power to the transmission shaft is arranged at the upper end of a cover with a transmission shaft arranged inside, and a valve that is displaced by the transmission shaft is arranged at the lower end, The transmission shaft of the power section is divided into two parts, a drive shaft part and a driven shaft part, and a manual handle having an input shaft approximately perpendicular to the transmission shaft is provided on the side of the cover, and the rotation of the drive shaft part and input shaft is controlled by
A water drain plug device characterized by being provided with a transmission switching mechanism that selectively transmits transmission to a driven shaft.
