造。[Claims for Utility Model Registration] A stopper bolt 7 for regulating the rotation range of the worm wheel 4 is externally screwed into a gear case 2 in which a worm wheel 4 interlocked with a valve stem 3 is internally installed. The cover 11 that covers the operating side of the stopper bolt 7 is attached to the stopper bolt 7.
In the valve operation reducer that also serves as a rotation prevention member, a tightening bolt 12 that presses the cover 11 against the gear case 2 is externally operable and rotatable relative to the cover 11, The cover 11 and the stopper bolt 7 are screwed substantially concentrically to the stopper bolt 7 to prevent relative rotation between the cover 11 and the stopper bolt 7. Engagement part 13 that allows separation
Stopper mounting structure for valve operation reducer equipped with. The stopper mounting structure according to claim 1, which is a registered utility model, wherein the cover 11 is formed with a concave-convex locking operation part 16 for rotating the cover.
