MISASSEMBLING PREVENTIVE STRUCTURE FOR TRANSMISSION GEAR

摘要

PROBLEM TO BE SOLVED: To provide misassembling preventive structure of a transmission gear allowing detection of misassembling at the time of finish of assembly of a transmission gear within a case. SOLUTION: In misassembling preventive structure of a transmission gear, a mark 43 is put on a gear 37s to be introduced finally in assembly of a transmission gear within a case. It is thus confirmed at the time of this final assemblage that relative positions of the gear 37s applied with the mark 43 and a gear 38s meshing with the gear 37s in mutual axial direction are in specific positional relation, by means of the mark 43.
