Abstract:
PROBLEM TO BE SOLVED: To provide an operation handle mechanism capable of moving a movable part by conveniently operating a handle, and capable of securing smooth operation and movement at all the time regardless of an operation position of the handle.SOLUTION: An operation handle part includes: a handle lever for operating a movement of a vertically movable support frame part 23; and left and right transmission rods 123a and 123b coupled to the handle lever. The transmission rod is displaceable by a predetermined distance in a moving direction relatively to the support frame part and moves integrally with the support frame part after exceeding the distance. The left and right transmission rods are coupled by rack parts 140a and 140b at a side of the transmission rods, gear trains 134a and 135b engaged with the rack parts, and gear trains 134b and 135b mutually engaged therewith in such a manner that a part of an operation force from the handle lever can be partially transmitted from one transmission rod to the other transmission rod and both the transmission rods can simultaneously move by an equal distance.
