Zusammenfassung:	A disc brake device (100) includes a rotating member (10), a brake disc (20), a control member (30), and a connecting member (40). The brake disc (20) includes an annular disc body (21) and a plurality of fins (22). The control member (30) includes a base plate (31) and a protrusion (32) for controlling the amount of air flow between the adjacent fins (22). At least one of the fins (22) has a connection hole (222) provided with a small diameter portion (222b). The base plate (31) has a through hole (311). A shaft portion (42) of the connecting member (40) passes through the small diameter portion (222b) and the through hole (311). The peripheral edge of the through hole (311) is arranged on the outer peripheral side of the peripheral edge of the small diameter portion (222b).
