[Claims for Utility Model Registration] It has a bucking plate and a plate-like shew web, forming an arc shape as a whole, and the shew web extends mutually on the bucking plate in a state substantially parallel to the bucking plate. A pair of brake shoes arranged to be openable, a strut spanning between the shoe webs of the pair of brake shoes, and a pin attached to the shoe web of one of the pair of brake shoes. a parking brake lever that is rotatably provided and rotated by a parking brake operating force in a direction substantially parallel to the shew web transmitted via a parking cable; The height positions on the king plate are substantially the same, and as the parking brake lever rotates in the brake operation direction, the parking brake lever pushes the strut and pushes the other brake shoe toward the outer circumference. In a drum brake equipped with a parking brake mechanism in which the parking brake lever pushes out the one brake shoe toward the outer circumferential side via the pin, a pair of brake shoes are provided on both sides in the plate thickness direction of the shoe web of the one brake shoe. The parking brake levers are rotatably provided by a common pin, and the parking cable is connected to the pair of parking brake levers at the center between the pair of parking brake levers, and when the parking brake is operated, the parking brake levers of the pair of parking brakes are connected to each other. A drum brake equipped with a parking brake mechanism, characterized in that the struts are simultaneously pushed toward the other brake shoe side by a lever.
