PROBLEM TO BE SOLVED: To provide a braking mechanism capable of preventing spreading during the assembling of a brake arm and a hard brake or during the operation by simple contrivance of a helical torsion spring. SOLUTION: The recording/reproducing device including a braking mechanism having a function for releasing a brake from a reel base by the reverse rotation of the reel base for rotary-driving a tape reel is provided with a brake arm 23 having a fulcrum shaft 22, a coil spring 16 for pressing the brake arm 23 to a tape feeding reel base side, a hard brake 25 attached to the brake arm 23 so as to be rotated and axially moved, and having a tooth part to be engaged with the tape feeding reel base, and a helical torsion spring 27 supported on the brake arm 23 to press the hard brake 25 to the tape feeding reel base side. One spring end 27b of the helical torsion spring 27 penetrates the hard brake 25, protruded from the brake arm 23, and provided with a holding piece 27c formed to be bent on its tip, and thus the pulling-out of the helical torsion spring 27 is prevented.
