Claims

[Scope of utility model registration request]

A rotating disc is fitted into the outer periphery of a center hub fitted to the drive shaft so as to be movable in the axial direction, a braking disc is axially opposed to the rotating disc and is fixedly attached to one side of the rotating disc, and A movable iron core provided on the other side of the disc so as to be movable only in the axial direction, a braking spring that performs a braking action by pressing the rotating disc against the braking disc via this movable iron core, and a braking spring for excitation of the electromagnetic coil. Accordingly, in a disc brake device comprising a fixed iron core that attracts a movable iron core against the braking spring, the center hub and the rotating disc are coupled so as to be movable in the axial direction at a polygonal fitting part, A pair of notches is provided in this fitting part, and the short side of the sound deadening spring consisting of a pair of short sides and long sides is passed through the notches, and the vicinity of the center of the long side is inserted into the rotating disk. A disc brake device characterized in that the muffling spring presses the rotating disc and the center hub in the radial direction by bringing them into contact with each other in the radial direction.
