A disk brake device has a rotary brake disk, at least one pad, and a mount. The pad has a guide portion disposed on one end of the pad in the rotational direction of the brake disk. The mount has a support portion that slidably supports the guide portion, so that the pad can move in the axial direction of the brake. A radially outer pressure receiving surface and a radially inner pressure receiving surface are formed on an end of the pad in the rotational direction of the brake disk and serve to receive a reaction force from the mount in order to prevent the pad from moving in the rotational direction of the brake disk. A support member serves to bias the pad in an axial and rotational direction so as to reduce the production of audible sounds.
