ABSTRACT:
A device for indicating gear positions in a gear selection mechanism for a manual vehicle transmission, preferably a transmission with four or more forward speeds. In the mechanism, a gear change lever is spherically mounted relative to the vehicle, and a gear change shaft is articulatedly connected to the gear change lever so as to convert lever movements during gear changing to angular and axial movements of the gear change shaft. When changing gears to and from a neutral position, such movements are divided into a selector step and an engaging or disengaging step, or vice versa. A first means of the gear change shaft coacts under spring bias with at least one second means of a bracket mounted in the vehicle. This coaction only has one stable position which corresponds to a given neutral position for the gear change lever. During the selector step the spring bias strives to return the first means to the stable position, thus indicating the gear position of the gear-change lever.
