Abstract: An exterior rearview mirror for motor vehicles has a mirror base and a mirror head connected to the mirror base. The mirror head is pivotable about a first pivot axis relative to the mirror base from a position of use into a parking position. A securing device exerting a securing force onto the mirror head at least in the parking position is provided. A tension spring exerting a spring force onto the mirror head is also provided, wherein the securing force counteracts the spring force. A cam disc is pivotably supported on the mirror base about a second pivot axis, wherein the mirror head has a support and wherein the tension spring has a first end connected to the cam disc and a second end connected to the support.
