Abstract:
In a brake device (1), each of a plurality of brake shoes (20) disposed on the radially inner side of an outer wheel (11) includes a first projecting portion (25A) and a second projecting portion (25B). Pairs of movable pieces (first rollers 81) are disposed between the first projecting portions (25A) and the second projecting portions (25B). An input side rotating member (40) includes, for each brake shoe (20), a first engaging portion (42A) disposed between the pair of movable pieces and the first projecting portion (25A), and a second engaging portion (42B) disposed between the pair of movable pieces and the second projecting portion (25B). When the input side rotating member (40) rotates in a first direction of rotation, the second engaging portions (42B) push the second projecting portions (25B), causing the brake shoes (20) to rotate in the first direction of rotation. When the input side rotating member (40) rotates in a second direction of rotation, the first engaging portions (42A) push the first projecting portions (25A), causing the brake shoes (20) to rotate in the second direction of rotation.
