<p><P>PROBLEM TO BE SOLVED: To provide a disc brake device having simple construction for producing a good stroke feeling during the operation of a parking brake and holding a braking gap between a friction pad and a disc rotor always good with reliable operation of an adjuster by fixing a spring retainer to prevent the rotation of a fixed side cam plate and the rotation of a thrust transmission plate in the state of being movable in the axial direction of a cylinder. <P>SOLUTION: The disc brake device comprises the spring retainer 13 having a mounting piece 13b protruded on the outer periphery on the bottom side of a cylinder hole, and a mounting bolt 24 inserted through a through-hole 13d of the mounting piece 13b and thread to a bottom wall 2e of the cylinder hole 2d to fix the spring retainer 13. An outer peripheral portion of the fixed side cam plate 11 is engaged with a shaft portion of the mounting bolt 24 to prevent the rotation of the fixed side cam plate 11, and an outer peripheral portion of the thrust transmission plate 15b is engaged therewith to prevent the rotation of the thrust transmission plate 15b in the state of being movable in the axial direction of the cylinder. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
