Abstract
A disc brake device for a vehicle, the disc brake device is equipped with: a piston slidably fitted into a cylinder hole provided in one arm section of a brake caliper, and capable of pressing against one friction pad; a shim plate mounted on a back plate of the one friction pad and interposed between the back plate and the piston; and a pressing device that applies pressing force to the piston while causing rotational force to act on the piston. Multiple protrusions protruding toward the piston are provided, with intervals between the protrusions, on the back plate of the friction pad facing the piston with the shim plate therebetween, and multiple engaging holes, into which the multiple protrusions are fitted, are provided on the shim plate so as to prevent the shim plate from rotating together with the piston due to the rotational force.
