Wiper motor, method for assembling a wiper motor, and assembly tool

A wiper motor having a gearbox housing, the gearbox housing comprising:

• a pot-shaped main body for configuring a receptacle space for a gearbox;
• wherein an opening of the pot-shaped main body is configured to close with a gearbox cover,
• wherein a plurality of latching connections are configured to act in a joining direction between the pot-shaped main body and the gearbox cover;
• said latching connections with a first latching element that is elastically deformable on the gearbox cover and a second latching element that is rigid on the main body, the second latching element configured to interact with the first latching element in a form-fitting manner;
• wherein the first latching element protrudes from a connection point in the joining direction by way of a tongue-type portion on the gearbox cover;
• the tongue-type portion portion being elastically deformable in a direction running perpendicular to the joining direction;
• wherein the second latching element in the joined state of the gearbox cover by way of a blocking portion that on the first latching element is disposed in a region of the tongue-type portion interacts with a blocking face on the first latching element;
• wherein the blocking portion has a ramp on a side that faces away from the main body, the depth of the second latching element increasing when viewed in the joining direction;
• wherein the ramp transitions to the blocking face;
• and
• wherein the tongue-type portion of the first latching element is configured so as to be free of any undercut either in a direction running perpendicular to the joining direction, or in a direction parallel to the extent of the tongue-type portion.
