To achieve prevention of falling of a tooth plate from a holding plate during assembly of a brake device.SOLUTION: A tooth assembly 50 of a brake device 7 has a holding plate 19 and a tooth plate 20. The holding plate 19 comprises: a boss part 19a in which a shaft hole 19b, in which a medium diameter shank 12b of a pinion shaft 12 is inserted, is formed; and an arm part 19d which extends in a radial direction from the boss part 19b, and is so formed as to be integrally bent in a stepped shape. A first shank 19e, that functions as a first support part rounded into a substantially cylindrical shape with a tip cut up is formed on the arm part 19d. Further, a cut-up piece 19i, that functions as a regulation part which projects to the tooth plate 20 side and engages with the tooth plate 20, is formed on the arm part 19d.SELECTED DRAWING: Figure 9

    【課題】ブレーキ装置の組み立て中におけるツースプレートの保持プレートから脱落防止を図る。【解決手段】ブレーキ装置7のツース組立体50は、保持プレート19とツースプレート20を有している。保持プレート19は、ピニオン軸12の中径軸部12bに挿入される軸孔19bが形成されたボス部19aと、ボス部19aから半径方向に延び、段付き状に一体に折り曲げ形成されたアーム部19dと、を備える。アーム部19dには、先端を切り起こすかたちで略円筒状に丸めた第1支持部として機能する第1軸部19eが形成される。さらにアーム部19dには、ツースプレート20側に突出して当該ツースプレート20に係合する規制部としての切起こし片19iが形成されている。【選択図】図9
