To obtain, for example, a vehicle drum brake which can keep a brake state mechanically and has an improved and new structure that enables further downsizing and improvement of responsiveness.SOLUTION: A vehicle drum brake of the disclosure includes:, for example, a first brake member and a second brake member facing an inner peripheral surface of a drum rotor; a brake mechanism which spreads a space between the first brake member and the second brake member to press the first brake member and the second brake member to the inner peripheral surface; a movable member which is provided so as to be movable between an interposed position, in which the movable member is interposed between the first brake member and the second brake member in a brake state that the first brake member and the second brake member are pressed to the inner peripheral surface by the brake mechanism, and a separation position, in which the movable member gets out of an area between the first brake member and the second brake member; and a driving mechanism which moves the movable member between the interposed position and the separation position.SELECTED DRAWING: Figure 1

    【課題】例えば、制動状態を機械的に保持することが可能な車両用ドラムブレーキであって、より小型化したり応答性をより高くしたりすることができるような、改善された新規な構成を有した車両用ドラムブレーキを得る。【解決手段】本開示の車両用ドラムブレーキは、例えば、ドラムロータの内周面に面した第一制動部材および第二制動部材と、第一制動部材と第二制動部材との間の間隔を広げることにより第一制動部材および第二制動部材を内周面に押し付ける制動機構と、制動機構によって第一制動部材および第二制動部材が内周面に押し付けられた制動状態で第一制動部材と第二制動部材との間に介在した介在位置と、第一制動部材と第二制動部材の間から抜け出た離脱位置と、の間で移動可能に設けられた可動部材と、可動部材を介在位置と離脱位置との間で動かす駆動機構と、を備える。【選択図】図1
