In the pushing anchor type disc brake device, reduction of noise and prevention of uneven wear can be accomplished especially in the brake device in which brake torque of the outer pad is transmitted via the caliper. In the disc brake device, the caliper is guided by a pair of guide pins composed of a main pin and a sub-pin. In order to transmit the brake torque of the outer pad via the caliper and the main pin, the back plate of the outer pad and the caliper are engaged with each other by engaging a protrusion with a recess, wherein the engagement is conducted at a plurality of portions in the circumferential direction of the rotor, so that the brake torque can be transmitted from the outer pad to the caliper. The main pin is arranged on the rotor run-out side, so that a pushing anchor structure can be formed. A pair of guide pins and guide holes of the support member which engage with the pair of guide pins stride the rotor and extend exceeding a facing section where the rotor faces the outer pad. The main pin is arranged on the rotor run-out side. Brake torque on the outer pad side is transmitted by the protrusion and recess engaging section arranged on the rotor run-out side.
