Abstract: A disc brake device includes a rotary member, a brake disc, and a control member. The brake disc includes a disc body having an annular shape and fins. The control member controls an airflow rate between the fins disposed adjacent to each other in a circumferential direction of the brake disc. The control member includes a base plate and a protruding portion. The protruding portion protrudes from the base plate toward the disc body. A top surface of each fin has a recessed portion. The protruding portion extends in the circumferential direction through from the recessed portion of one of the fins disposed adjacent to each other to the recessed portion of the other of the fins.

Abstract: A brake disk includes a ring body in a ring groove on a side of a friction ring which is not acted upon for connecting the mutually opposite ends of friction ring segments with one another. The ring bodies prevent an expanding of the juncture caused by centrifugal force as well as a radial relative displacement of the ends of the ring segments, while a limited relative rotation of the faces of the ring segments is possible when an air gap exists at the juncture.
