Claims

[Claims for Utility Model Registration] An anchor fixed on a bucking plate, in which one end of a pair of brake shoes facing each other is brought into contact with a side surface of the pair of brake shoes, which are provided so as to be able to expand with respect to each other on the bucking plate. a member, a pair of latching protrusions provided on the distal end side of the anchor member and protruding from each other in a direction away from the bucking plate at positions spaced apart from each other by a predetermined distance, and a hook portion at one end in the axial direction. , with the hook portions being respectively latched on the latching protrusions, each is stretched between the latching protrusion and both brake shoes, and one end of the brake shoe is directed toward the anchor member. In a drum brake equipped with a pair of biasing springs, a surface of the latching protrusion that is substantially opposite to the axis of the spring latched to the latching protrusion and opposite to the spring side. An engagement that is recessed toward the spring side on a surface located on the side and engages with the vicinity of the tip of a rod-shaped latching tool inserted into the hook portion in order to latching the hook portion to the latching protrusion. A drum brake characterized by having a recessed part.
