<P>PROBLEM TO BE SOLVED: To solve the following problems that in the example of pruning scissors for garden trees, long handles are used in order to obtain large output with little input utilizing the principle of a lever in conventionally used scissors, the work of largely widening the handles long on the outer side and narrowing them to the inner side with both arms is needed in order to open and close blades, fatigue in pruning work is huge and operability in a narrow place is bad. Ž<P>SOLUTION: In the force transmission structure, an output operation member or an output member of another kind is connected at a turning fixation part at a part near a folding point, two connection arms are connected at the turning fixation part at one end part of each, the turning fixation part at the other end part is connected to the turning fixation part at the intermediate part of two input arms respectively, the turning fixation part at the intermediate part of the connection arm and the turning fixation part at the part other than the acting part of the output operation member are respectively connected at the turning fixation part at both end parts of a force transmission arm respectively, and the turning fixation part at the end part of an input arm is connected with the turning fixation part at the part near the folding point of the output operation member or the turning fixation part at the part other than the acting part.
