ABSTRACT:
A tape measure has a case, a measuring tape coilable therein, a return spring and a carrier turned by the spring to retract the measuring tape. Excessive speed of the carrier is reduced by rotational imbalance which induces wobble and so causes the rotating carrier to strike adjacent fixed structure and be frictionally retarded. The carrier has its radially inner and outer parts connected through a flexible link, and may include an eccentric drum for the blade to coil around.
