- 車体(11)に揺動可能に枢支されてブレーキケーブル(14)を牽引するように引き上げられるパーキングブレーキレバー(13)と、
前記パーキングブレーキレバー(13)に支点ピン(18)を介して枢支されたラチェットポール(19)と、
前記ラチェットポール(19)の係止爪(19c)が係合可能な複数の係止歯(17a)および係止溝(17b)を交互に備えて車体に固定されたラチェットプレート(17)と、
乗員の解除操作により前記ラチェットポール(19)を押圧することで、前記係止爪(19c)を前記係止溝(17b)から係合解除する方向に前記ラチェットポール(19)を揺動させるリリースロッド(23)と、
を備えるパーキングブレーキ装置において、
前記ラチェットポール(19)と前記支点ピン(18)との間に所定のクリアランスが設けられ、
前記係止歯(17a)および前記係止爪(19c)の歯先同士が接触している状態で、前記ラチェットポール(19)および前記リリースロッド(23)の接触点(b)と、前記係止歯(17a)の円弧の中心(O1)と、前記係止爪(19c)の円弧の中心(O2)とが一直線上に存在するときの第1の直線の方向に対し、
前記係止歯(17a)および前記係止爪(19c)の歯先同士が接触している状態で、前記支点ピン(18)および前記ラチェットポール(19)の接触点(a)と、前記係止歯(17a)の円弧の中心(O1)と、前記係止爪(19c)の円弧の中心(O2)とが一直線上に存在するときの第2の直線の方向が異なるように設けられ、
前記ラチェットポール(19)は前記リリースロッド(23)に対して相対移動可能であることを特徴とするパーキングブレーキ装置。 - 前記パーキングブレーキレバー(13)の乗員の引上力と前記ブレーキケーブル(14)の張力とが略同等であるときに、前記リリースロッド(23)の前記ラチェットポール(19)に対する押圧力により前記係止歯(17a)および前記係止爪(19c)の歯先同士が接触し、この状態で前記第1の直線が存在する場合には第1の釣合い状態となり、 前記パーキングブレーキレバー(13)の乗員の引上力が略ゼロであるときに、前記ブレーキケーブル(14)の張力により前記係止歯(17a)および前記係止爪(19c)の歯先同士が接触し、この状態で前記第2の直線が存在する場合には第2の釣合い状態となり、
前記第1の釣合い状態および前記第2の釣合い状態は、前記第1の直線が存在するときの前記釣合い状態と、前記第2の直線が存在するときの前記釣合い状態とがそれぞれ発生する前記係止歯(17a)および前記係止爪(19c)の接触点(c)を中心に所定の領域(S1,S2)内で発生するものであり、
前記第1の釣合い状態が発生する領域(S1)と、前記第2の釣合い状態が発生する領域(S2)とは互いに重なり合わないことを特徴とする、請求項1に記載のパーキングブレーキ装置。
