1. Blocking mechanism for rotationally blocking a shaft of a vehicle having at least one locking recess, the blocking mechanism comprising:
a transmission casing;
a movable pawl comprising a locking finger, the movable pawl being pivotably mounted in a plane about a pivot axis on the transmission casing between a locking position in which the locking finger is engaged in one of the at least one locking recess and a release position in which the locking finger is disengaged from one of said at least one locking recess, the movable pawl comprising a cam surface,
a linear actuator which moves a movable carriage guided by a guide rail, in which the movable carriage includes a cam follower capable of moving on the cam surface so as to move the movable pawl from the release position into the locking position,
a housing formed in the transmission casing, in which the guide rail is fitted in the housing so as to prevent movement of the guide rail in the plane,
wherein the housing has a first side wall facing and at a distance from a second side wall and a first longitudinal wall located between the first side wall and the second side wall, wherein the guide rail has, corresponding to the housing, a first side wall facing and at a distance from a second side wall and a first longitudinal wall located between the first side wall and the second side wall, and
wherein the first side wall, the second side wall and the first longitudinal wall of the guide rail are in contact, respectively, with the first side wall, the second side wall and the first longitudinal wall of the housing.
