<p><P>PROBLEM TO BE SOLVED: To provide a technique to reduce unevenness of mating face pressure between a disk rotor and a brake pad. <P>SOLUTION: The disk brake device consists of a friction material 32 provided to face against a friction sliding surface of the disk rotor 26 rotating with a wheel, a back metal member 30 having a supporting surface 64 for supporting a surface which is not facing against the disk rotor of the friction material 32 and a surface with a slant surface 60 formed in it, a contact member 34 contacting with the slant surface 60 and a piston 46 for pressing the contact member 34 in a direction parallel to a rotation shaft of the disk rotor 26 and pressing the friction material 32 to the friction sliding surface of the disk rotor 26. The slant surface 60 formed in the back metal member 30 is provided to face against it in approximately parallel and the contact member 34 has a slant surface 70 contacting with the slant surface 60. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
