To obtain a drum brake of a new configuration with less inconvenience, for example, so as to reduce labor and cost of manufacture furthermore.SOLUTION: A drum brake includes: for example, an electric actuator provided in the inside in a vehicle width direction from an inner surface, and having a housing, a motor, a rotating member rotated by the motor, and a direct drive member directly driven according to the rotation of the rotating member, and moving a movable member so that a brake-shoe may move between a non-braking position and a braking position; and a supporting member having a biasing member positioned in the outside of a vehicle width direction of an outer face and biasing a brake-shoe in the inside of the vehicle width direction, a first support part penetrating the backing plate in the vehicle width direction and supporting the biasing member, and a second support part supported by a third support part provided at the housing or a connecting member connected to the housing.SELECTED DRAWING: Figure 2

    【課題】例えば、より製造の手間やコストを低減することを可能とするような、より不都合の少ない新規な構成のドラムブレーキを得る。【解決手段】ドラムブレーキは、例えば、内面よりも車幅方向内側に設けられ、ハウジングと、モータと、当該モータによって回される回転部材と、当該回転部材の回転に応じて直動しブレーキシューが非制動位置と制動位置との間で動くように可動部材を動かす直動部材と、を有した電動アクチュエータと、外面の車幅方向外側に位置しブレーキシューを車幅方向内側に付勢する付勢部材と、バッキングプレートを車幅方向に貫通し、付勢部材を支持する第一支持部と、ハウジングまたは当該ハウジングに接続された接続部材に設けられた第三支持部に支持された第二支持部と、を有した支持部材と、を備えている。【選択図】図2
