1. A vehicle-sensitive sensor for a self-locking belt retractor, comprising:
a support part,
a sensor mass which is disposed vertically on a contact surface of the support part and can tilt relative to the support part and
a locking lever which is coupled to the sensor mass and has an engagement tip, wherein the locking lever has at least two rotation elements for forming an axis of rotation for the locking lever, and
wherein each rotation element rests on an associated contact point of the support part,
wherein the support part has a recess for each rotation element with each recess having a front opening by means of which the rotation element can be introduced into the recess, and
wherein a base of the recess forms a contact point, wherein the base is covered by a cover of the respective recess and each opening narrows towards the base of the recess.
