パイプの取付け構造。 A pair of brake shoes are pivoted to face the back plate inside a brake chamber sealed between the back plate and the brake drum, and one end of both brake shoes on the rotation fulcrum side is anchored. In a closed type vehicle drum brake in which the other end of the expansion side is supported in contact with an actuator, the anchor is arranged on an anchor block disposed on the back plate side and on a side surface of the anchor block opposite to the back plate. A through hole is formed in the anchor block and the back plate to communicate the brake chamber with the outside, and one end of the brake shoe is supported on the side wall of the anchor block, and the anchor plate has a through hole that communicates the brake chamber with the outside. , a pair of projecting pieces protruding from the side wall of the anchor block to resiliently support one end of the brake shoe, and a breather pipe connecting pipe inserted into the through hole are integrally provided, and a tip end of the breather pipe connecting pipe is provided. A breather pipe mounting structure in a sealed vehicle drum brake, characterized in that the breather pipe is protruded from the outside of the back plate to serve as a connection port for the breather pipe.
