いことを特徴とするバルブ停止装置。A stop device for a valve that is reciprocally driven by a cam to open and close a port, and includes a lifter that is reciprocally driven by the cam, and a lifter that is housed in the lifter and that constantly positions the center of gravity directly above the valve stem. a transmission member that is rotatable around a substantially vertical axis and has a hole through which the valve stem can be inserted, both of which contact the valve stem; and a transmission member that is provided in the lifter and regulates rotational displacement of the transmission member. a stopper; and a control mechanism capable of rotationally displacing the transmission member around the axis to align the hole with the valve stem, the control mechanism positioning the transmission member in a position where the hole is not aligned with the valve stem. When rotationally displaces the valve, the valve opens and closes the port by reciprocating the transmission member in conjunction with the movement of the cam, and the control mechanism moves the transmission member to a position where the hole aligns with the valve stem. A valve stop device characterized in that, when the transmission member is rotated and displaced, even if the transmission member reciprocates in conjunction with the movement of the cam, the valve stem does not open the port because the valve stem fits into the hole.
