[Claims for Utility Model Registration] A pair of brake shoes disposed on a bucking plate, each having a shoe web having an arc shape and a notch opening toward the inner circumference in the longitudinally intermediate portion thereof. The drum brake has a shaft portion and a head provided at one end of the shaft portion and protrudes a predetermined distance from the shaft portion in a direction perpendicular to the shaft center, and the bucking plate is attached to the other end side of the shaft portion. A state in which the shaft portion is swingably attached to the shaft portion, and the intermediate portion of the shaft portion has a shoot-hold down pin that is inserted into the cutout of the shoot web, and a through hole, and the shaft portion is inserted into the through hole. a first cup disposed between the head and the show web, located on the head side and prevented from coming off by contact between the head and the periphery of the through hole; and a first cup located on the show web side. and a coil spring interposed between the two cups with a predetermined preload applied thereto, and the brake shoe is supported on the bucking plate in a state in which the brake shoes can be mutually expanded. The shoe-hold down device is a shoe-hold down device, wherein the shoe-hold down pin is attached to a portion of the head of the shoe-hold down pin that comes into contact with the peripheral edge of the through hole of the first cup, from the base of the head toward the tip. A hold-down device for a drum brake, comprising a tapered surface inclined at a predetermined angle in a direction away from the axis of a hold-down pin.
