WATCH OPERATING CAM STRUCTURE, CHRONOGRAPH MECHANISM WITH THE STRUCTURE, MOVEMENT AND CHRONOGRAPH WATCH WITH THE MECHANISM, AND ADJUSTMENT METHOD OF WATCH OPERATING CAM STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a watch operating cam structure capable of suppressing to a minimum occurrence of an auxiliary push stop phenomenon, in a stop operation, caused by variety or the like in shapes and dimensions of levers directly or indirectly engaged to the watch operating cam structure, a chronograph mechanism with the structure, a coronograph watch with the mechanism and an adjustment method of the operating cam structure.;SOLUTION: A watch operating cam structure 1 of a chronograph mechanism 2 of a chronograph watch 4 comprises a ratchet gear part 30 and a skewer gear part 40 so as to relatively displace them around a first center axial line C that is a center axial line of the ratchet gear part and the skewer gear part, and includes adjustment means 50 for fixing the ratchet gear part and the skewer gear part at relative positions adjusted around the first center axial line. The adjustment method includes adjusting relative rotation phases of the ratchet gear part and the skewer gear part by operating the adjustment means 50 via an opening 8a which is formed in a support substrate 8 opposing the operating cam structure 1.;COPYRIGHT: (C)2014,JPO&INPIT
