Abstract
Provided is an operation handle mechanism with which a handle can be conveniently operated to move a movable section, thereby ensuring smooth operation and movement at any time regardless of an operation position of the handle. An operation handle sectionincludes a handle lever, which is used to operate movement of a support frame sectioncapable of moving up and down, and left and right transmission rodsand, which are joined to the handle lever. The transmission rods can only move a predetermined distance in a movement direction thereof relative to the support frame section, and start to move together with the support frame section after going beyond that distance. The left and right transmission rods are connected via rack sectionsandof the transmission rods and a gear train, andmeshing with the rack sections in such a way as to enable transmission of part of an operation force coming from the handle lever from one transmission rod to the other and thereby allow the two transmission rods to simultaneously move only the same distance.
