Abstract: Provided is a drum brake comprising a shoe hold mechanism that improves tracking of the movement of brake shoes. A shoe hold pin of the shoe hold mechanism provided to the drum brake has: a base part that is locked to a back plate; a shaft part that is provided continuous from the base part, and a distal-end head part that is provided continuous at an axial end part of the shaft part, an engaging part provided to a shoe hold spring being engaged with the distal-end head part. A protruding part (contact part) with which the engaging part is brought into contact is provided at a position spaced from the distal-end head part toward the shaft-part side. The shoe hold mechanism makes it possible to improve the tracking of the movement of first and second brake shoes.
