To reduce a load of a control member, mounted on a railroad vehicle disk brake device, to control a ventilation volume of a ventilation passage.SOLUTION: A disk brake device (100) comprises a rotary member (10), a brake disk (20), a control member (30) and a fastening member (40). The brake disk (20) has an annular disk body (21) and a plurality of fins (22). The control member (30) has a base plate (31) and protrusion sections (32) and controls a ventilation volume in a space between the neighboring fins (22). At least one of the fins (22) has a fastening hole (222) including a small diameter section (222b). The base plate (31) has a penetration hole (311). A shaft section (42) of the fastening member (40) is inserted through the small diameter section (222b) and the penetration hole (311). A peripheral edge of the penetration hole (311) is arranged in an outer peripheral side of a peripheral edge of the small diameter section (222b).SELECTED DRAWING: Figure 4

    【課題】通気路内の通気量を制御するための制御部材が設けられた鉄道車両用ディスクブレーキ装置において、制御部材に対する負荷を低減する。【解決手段】ディスクブレーキ装置(100)は、回転部材(10)と、ブレーキディスク(20)と、制御部材(30)と、締結部材(40)とを備える。ブレーキディスク(20)は、環状のディスク本体(21)と、複数のフィン(22)とを有する。制御部材(30)は、ベースプレート(31)と、突出部(32)とを有し、隣り合うフィン(22)の間の通気量を制御する。フィン(22)の少なくとも1つは、小径部(222b)を含む締結孔(222)を有する。ベースプレート(31)は、貫通孔(311)を有する。小径部(222b)及び貫通孔(311)には、締結部材(40)の軸部(42)が挿通される。貫通孔(311)の周縁は、小径部(222b)の周縁の外周側に配置される。【選択図】図4
