The disk brake device includes a brake disk, a brake lining, and a brake caliper. The brake lining includes a friction member and a base plate for supporting the friction member. When a plurality of bolt holes are projected onto a rear face of the base plate in a direction of an axle, a boundary passes through areas of the projected bolt holes. The brake caliper includes an inner pressing surface that applies a load on an inner area and an outer pressing surface that applies a load on an outer area. The load applied on the inner area from the inner pressing surface is different from the load applied on the outer area from the outer pressing surface. In this way, it is possible to suppress stress imposed on bolts while suppressing a local temperature rise in the brake disk.
