A drum brake includes a brake drum attached to an axle, and a brake panel. The brake drum includes a disc portion and a cylindrical portion extending from an outer peripheral end portion of the disc portion towards the brake panel. On an outer peripheral end portion of the cylindrical portion, there is mounted a seal member. The brake panel includes an annular flat surface portion, and a cylindrical projecting portion projecting from an outer peripheral end portion of the annular flat surface portion towards the brake drum so as to surround the seal member. The seal member has plural resilient axial sealing lips and at least one resilient radial sealing lip. The axial sealing lips are in sealing contact with the annular flat surface portion, and the radial lip is in sealing contact with an inner peripheral surface of the cylindrical projecting portion. Even if the brake drum is axially displaced away from the brake panel due to accidental bending of the axle, the radial sealing lip remains sealingly contact with the inner peripheral surface of the projecting portion.
