Claims

[Scope of utility model registration request]

A brake drum that is rotatably supported by the vehicle body, is integrally fixed to the wheels, and has an outer circumferential surface; and a brake drum that is fixed to the vehicle body and has a U-shaped recess in the outer circumference, forming a first labyrinth together with the brake drum. A drum brake comprising: a back plate; and a tast cover that is fixed to the outer circumference of the back plate, extends to surround the outer circumference of the brake drum, and defines a space between the outer circumference of the back plate and the brake drum. The proximal end of the annular member is fitted onto the outer peripheral surface of the annular member, and the distal end of the annular member is loosely inserted into the space so that the distal end of the annular member forms a second labyrinth together with the back plate and the dust cover. A driver and brake featuring.
