<p><P>PROBLEM TO BE SOLVED: To stably suppress brake noise regardless of the magnitude of braking force while upsizing of a device is inhibited. <P>SOLUTION: A disk brake device 100 is equipped with an annular disk rotor 10 fixed to an axle, a pad member 20 which makes contact with the disk rotor 10 in the axle direction, and a caliper 30 which movably supports the pad member 20 in the axle direction and suppresses circumferential and radial movements of the disk rotor 10, wherein the caliper 30 is equipped with a fixing section 31 for fixing the caliper 30 to car body side and a cylinder mechanism 32 pressing the pad member 20 to the disk rotor 10 from the axle direction, the pad member 20 is equipped with a projection section 23 projected in radial inner direction, and the caliper 30 is equipped with a groove section 35 housing the projection section 23 and restricting the movement of the projection section 23 toward a trailing side or a leading side and a radial restricting section restricting the movement of the pad member 20 toward the radial outer direction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
