Vehicle drum brake

In the interior of a brake drum, the arrangement space in the rotational axis direction of the brake drum is spacious in comparison with that in the direction orthogonal to the rotational axis direction in which an anchor portion, hub components on the vehicle body side and the like are arranged. An electric parking brake device is provided with the anchor portion that supports respective one ends of brake shoes. A parking lever is pivotally moved by a drive unit operated by an electric motor for pushing the brake shoes toward the brake drum. The anchor portion and the drive unit are arranged to be piled up in the rotational axis direction of the brake drum which is spacious in comparison with the direction orthogonal to the rotational axis direction.
