The object of the present invention is to provide a synchro-spring to be used in a synchronizing mechanism having insert-shifting keys. Said synchro-spring is characterized by shaping convex forms in the portions which come into contact with said insert-shifting keys, and when this synchronizing mechanism is used for an automobile transmission, an enough capacity of the synchronizer ring can be ensured without increasing the size of the synchronizing mechanism, and smooth gear shifting is attained, and then excellent operability can be acquired. <IMAGE> |
