Patent abstract
Disclosed herein is a tape measure with a self-regulating speed control mechanism. In the present invention, when a bobbin rotates, a rubber roller rotatably provided on a movable mounting plate alternately comes into contact with an inner surface of a support ring and a rubber acceleration prevention member provided on the inner surface of the support ring, so that the speed of the bobbin can be smoothly and reliably reduced.
