Kind Code:

Abstract:

The disk brake device (1) includes a brake disk (2), a brake lining (3), and a brake caliper (4). The brake lining (3) includes a friction member (9) and a base plate (10) for supporting the friction member (9). When a plurality of bolt holes (7) are projected onto a rear face (13) of the base plate (10) in a direction of an axle (5), a boundary (16) passes through areas of the projected bolt holes (7). The brake caliper (4) includes an inner pressing surface (17) that applies a load on an inner area (14) and an outer pressing surface (18) that applies a load on an outer area (15). The load applied on the inner area (14) from the inner pressing surface (17) is different from the load applied on the outer area (15) from the outer pressing surface (18). In this way, it is possible to suppress stress imposed on bolts while suppressing a local temperature rise in the brake disk.
