Lock for a flap or door

A lock for a door or flap comprising:

• a lock housing,
• a locking mechanism including a rotary latch and a main locking pawl, wherein the main locking pawl is pivotable between an initial position in which the rotary latch is open and an end position in which the rotary latch is locked,
• and a spring able to pivot the main locking pawl of the locking mechanism by means of spring force from the initial position in a direction of the end position,
• wherein the lock has a bearing mandrill and a stop for the spring, the stop and the bearing mandrill being formed with the lock housing as a single piece of common material, and the spring is held by the bearing mandrill connected to the lock housing, and the stop for the spring ensures that in the end position no spring force acts on the main locking pawl, and in the initial position the spring is disengaged from contact with the stop;
• wherein the locking mechanism further includes an intermediate locking pawl having a surface that presses against the rotary latch in an intermediate locking position when the main locking pawl is in an intermediate position between the initial position and the end position, and the spring force of the spring acts on the main locking pawl when the rotary latch is in the intermediate locking position;
• and
• wherein the intermediate locking pawl and the main locking pawl rotate about a common axis of rotation.
