Abstract

In a changing system in a manual transmission in which a reverse idling gear is slid and meshed simultaneously with a first reverse gear secured to one of a main shaft and a counter shaft and with a second reverse gear mounted on a sleeve of a preselected synchronizing mechanism mounted on the other of the main shaft and the counter shaft, thereby establishing a reverse speed stage, an interlock plate is formed into a shape for inhibiting the movement of a preselected shifting piece in the same direction as a direction of sliding of the reverse idling gear, when a shifting arm having a drive portion engaged with a reverse shifting piece is turned for shifting to establish a reverse speed stage. Thus, it is possible to inhibit the movement of the sleeve of the preselected synchronizing mechanism, when the reverse speed stage is to be established.
