A safety gear e.g. for an elevator car or counterweight, comprises at least one wedge chamber (8) and at least one working wedge (9) acting on an elevator guide rail (30) and activated by a transmission element. For each working wedge (9), the safety gear has at least one counter wedge (10) moving along guide surfaces (14 and 39) provided in the wedge chamber (8). The counter wedge (10) of a working wedge (9) is on the same side of the guide rail as the working wedge (9) in question.
