To provide a disc brake device capable of rapidly eliminating a cause of noise between a brake pad and a disc rotor, and capable of notifying that when abrasion reaches an abrasion limit value.
Torque receiving grooves 34a and 34b are tilted to an inner peripheral side of the disc rotor 18 when the brake pad 14 is pushed to the disc rotor 18. The brake pad 14 is provided with an abrasion notifying member 38 abutting with the disc rotor 18 when being tilted to a predetermined value or more to the inner peripheral side of the disc rotor 18 from an initial position and notifying that abrasion on an abrasion sliding surface exceeds the predetermined value. The brake pad 14 is tilted in accordance with progress of abrasion, and is moved to the disc rotor 18. As a result, an abutting position of the brake pad 14 and the disc rotor 18 is moved, and a foreign matter can be delivered. When abrasion exceeds the limit value, the abrasion notifying member 38 is abutted to the disc rotor 18, and generates a warning.
