A drive for actuating a flap pivotably supported in or on an automobile includes a push-push kinematics. The kinematics includes a pushbar axially displaceably supported in a housing and having an external actuation end cooperating with the flap. A rotatable ring encloses the pushbar. A groove runs parallel to the pushbar axis and engages with a protrusion at the inner circumference of the ring. A first deflection face runs obliquely to the pushbar axis and cooperates with the protrusion of the ring to rotate this ring when the pushbar is pushed into the housing. A locking recess situated at the pushbar for receiving the protrusion when the pushbar is released, to lock the pushbar in the housing. A second deflection face runs obliquely to the pushbar axis and cooperates with the protrusion when the pushbar is moved out of the locked position by being pushed farther into the housing.
