動機構。 A first member that presses a reel disk of a device for recording and reproducing signals on a running magnetic tape to apply a braking force to the reel disk, and a second member whose rotational position changes depending on the mode of the device. are provided coaxially so as to be independently rotatable, and a torsion coil spring that applies a pressing force to the reel disk to the first member has one end attached to the second member and the other end attached to the first member. The spring force of the torsion coil spring changes depending on the rotational position of the second member, and the braking force changes to the mode of the device. A reel-disk braking mechanism for a magnetic tape recording/reproducing device configured to be variably set to suit the user.
