As is clear from the above explanation, the disc-shaped caliper support bracket supported by the axle covers the brake disc from its outer surface, and is formed from the outer circumference of the integrally molded caliper support bracket toward the axle. The caliper, which is equipped with a pair of friction pad pieces, straddles the brake disc from the inner periphery, and the caliper support bracket straddles the brake disc from the inner periphery in correspondence with both side walls of the notch. A disc brake device has been proposed which is characterized by having a pair of protrusions spanning from the sides, and in which pressure receiving surfaces for friction pad pieces are formed on the pair of protrusions and the both side walls.

A protrusion is formed on the caliper support part of the caliper support bracket so as to straddle the brake disc from its inner circumferential side, and a pressure receiving surface for the friction pad piece is provided on the protrusion, and a friction pad piece is also provided on the side of the caliper support bracket main body. Since the pressure receiving surfaces are provided, the friction pad pieces are supported in contact with the pressure receiving surfaces corresponding to the pair of friction pad pieces, respectively, and stable braking is performed.

The protruding portion is formed to protrude only from the caliper support portion, so that the caliper support bracket can be formed thin as a whole, and the weight can be sufficiently reduced.

In the caliper straddle type, in which the caliper straddles the brake disc from the inner circumference, the support point of the caliper is close to the axle, which is disadvantageous in terms of receiving torque during braking. Since a structure is adopted in which the torque is received by the notched side wall portion and the protruding portion, a large burden is not placed on the caliper itself, and the caliper can be made smaller and lighter.
