The present invention discloses a tape measure structure with improved brake device wherein the tape measure comprises a tape; an enclosure; and a brake device which further includes a release key and two brake shoes. By means of the above combination, the withdrawal motion of the tape can be controlled by the user through simply pressing the release key with his finger. It means that the user may pull out the tape to approximately estimated length he desires for measurement without worrying about that the tape might automatically bounce back. Then afterwards he may press lightly the release key to withdraw the tape gradually and stops pressing the release key as soon as the tape reaches to the accurately desired length, the tape will be halted there by the control effect of the brake device.
