Claims

[Claims for Utility Model Registration] A conical surface that is disposed on the side of a synchronizer of a specific forward stage of a manual transmission, connects a primary shaft and a secondary shaft with each other, and contacts a synchronizer ring of the synchronizer. a thrust washer that is in contact with the synchronizer ring and is prevented from rotating by the reverse synchro gear; and a thrust washer that is interposed between the thrust washer and the reverse synchro gear and that moves the synchronizer ring away from the conical surface. 1. A shift device for an automobile gear transmission, comprising a biasing member that biases the transmission.
