Synchronizer and a used for a synchronizer pre-synchronization sliding piece, the pre-synchronization sliding piece comprising a support - - sliding part, a positioning pin, a receiving chamber as well as in the receiving chamber has a spring and a positioning ball, wherein the positioning ball in the opening of the receiving chamber is positioned; and the positioning pin and the support - - sliding part is formed separately and are connected to one another. Since the positioning pin and the support - - sliding part are formed separately, in a mounting in different types of synchronisers and with different dimensions in the case of unsuitable dimensions of the support - - sliding part or of the positioning pin in the pre-synchronization sliding piece of the new construction of the molding tool as well as the processing and shaping for only one of the two components is sufficient, whereas the forming tool of the other component does not have to be changed, so that the product - and time costs can be lowered. For example, are in most cases, the demands on the dimensions of the support - - sliding part in different types of synchronisers different, for which reason the positioning pin can be constructed as a standard component, while in the case of support - - sliding part of the shaping tool for the preparation in accordance with the requirements on the dimensions are changed and can be produced.
