A disk brake device includes a pair of brake disks and right and left pairs of pads. Each pad includes a twisting compliant section that extends along a line inclined by an angle relative to a radial direction of the corresponding brake disk. The twisting compliant section facilitates the twisting of the pad about the compliant section. The twisting compliant sections of the right inner pad and the left inner pad are inclined in opposite directions relative to the twisting compliant sections of the right outer pad and the right inner pad. The twisting compliant sections of the right inner pad and the left inner pad are inclined in substantially the same direction with one another.
