Abstract: An electric parking brake device includes an inner engaging part formed on an inner shim, wherein the engaging part engages with a projection projecting from the back face of an inner brake pad so that mutual rotation about the central axis of a piston is controlled. An outer hook is formed on an outer shim, wherein the outer hook slidably locks to the outer circumferential edge of an outer brake pad. The outer hook is configured so that at least one of same is provided on each of an outer circumferential end on the outside of and an outer circumferential end on the inside of the outer brake pad in the radial direction and so that the set spring constant allows the outer shim to move to the outside in the radial direction with respect to the outer brake pad while the parking brake is applied.
