A reel brake device for a tape reel of a magnetic tape cassette has a pair of braking strips for a supply reel and a take-up reel. The braking strips are formed at least one hinged section to allow resilient deformation in order to absorb kinematic energy to be exerted on the braking strips from the tape reel as the reel subject rotational torque or lateral force. By providing the capability of resilient deformation for for the braking strips braking, engagement can be maintained even when vibration exerting rotational force to the tape reels is applied.
