PURPOSE:To delay a self-energizing force to improve a brake feeling by fixing a tubular body to a back plate and forming a step in a through hole of the tubular body so that a spring is compressively provided between the step and a floating rod. CONSTITUTION:A connecting device 11 for interconnecting brake shoes 2, 3 is constituted of a tubular body 12 fixed to a back plate 1 and a floating rod 13 movably provided in a through hole 12a of the tubular body 12. The through hole 12a is formed with a large diameter portion from an opening portion at the brake shoe 2 side to the deep portion to form a step 12b in through hole 12a. And a spring 14 is compressively disposed between a step 12b and a collar 13e of a rod member 13a projecting into the circle of the large diameter hole portion. |
