たことを特徴とする車両用ドラムブレーキ装置。A vehicle drum in which a pair of brake shoes provided on the inner surface of the back plate is used as a fulcrum by abutting one end of each brake shoe against an anchor fixed to the back plate, and the other end is expanded for braking action. In the brake device, a shoe web abutting surface is provided on the head of the mounting bolt for fixing the anchor, a flange extending in the shoe web direction on the head end side of the shoe web abutting surface, and a flange portion that is abutting against the reeding force. Anchor contact surfaces are formed in contact with each other, and the anchor is formed with a tightening seat surface having an insertion hole for the mounting bolt penetrating through the back plate side, and a pressure receiving surface continuous with the tightening seat surface. , a stopper member is provided on the head end side of the mounting bolt, the shaft portion passing through the mounting hole of the back plate to fasten and fix the anchor to the back plate, and a stopper portion for preventing the mounting bolt from coming off. A drum brake device for a vehicle, characterized in that the stopper member is provided with a spring member which is engaged with the anchor and further presses the head of the mounting bolt toward the pressure receiving surface of the anchor.
