To provide a brake shoe mounting structure of a unit brake device capable of detaching a brake shoe from a shoe head in a state where a pipe is connected to a dust collection unit.SOLUTION: A brake shoe mounting structure of a unit brake device comprises: a shoe head 37 provided with a recess part 37A into which a mounting plate 44 of the brake shoe 2 is fitted; a shoe cotter 46 that is inserted into the recess part 37A and an opening part formed in the mounting plate 44, to mount the brake shoe 2 to the shoe head 37; and a first dust collection unit 50A and a second dust collection unit 50B that collect wear powder generated when the brake shoe 2 is pressed against a tread. The first dust collection unit 50A and the second dust collection unit 50B are provided outside an insertion path of the shoe cotter 46.SELECTED DRAWING: Figure 2
【課題】配管が集塵部に接続された状態で、制輪子をシューヘッドから脱着することができるユニットブレーキ装置の制輪子取付構造を提供する。【解決手段】ユニットブレーキ装置の制輪子取付構造は、制輪子2の取付板44が嵌る凹部37Aが設けられたシューヘッド37と、凹部37A及び取付板44に形成された開口部に挿入されて、制輪子2をシューヘッド37に取り付けるシューコッタ46と、制輪子2が車輪の踏面に押し付けられることで生じる摩耗粉を集塵する第1集塵部50A及び第2集塵部50Bと、を有する。第1集塵部50A及び第2集塵部50Bは、シューコッタ46の挿入経路外に設けられる。【選択図】図2
