Abstract
A gearbox includes a transmission casing and a blocking mechanism for a vehicle. The blocking mechanism includes a pawl having a locking finger able to be engaged in a locking recess, an actuator which moves a mobile carriage having first and second rollers, and a guide rail attached to the casing. The guide rail forms an attachment wall and a guide wall, the first roller being placed in contact with the second roller and with the pawl, and the second roller being placed in contact with the guide wall. The guide rail is attached to the casing by an attachment mechanism, the guide rail and the attachment mechanism collaborating in such a way that the attachment wall is held against the casing while being able to be moved relative to this same attachment mechanism.
