To provide a brake caliper device capable of securing a stroke amount of a piston even when an initial position of arms changes, and achieving sufficient brake force.SOLUTION: A brake caliper device includes a clearance adjustment mechanism 4 capable of adjusting an initial position of a brake pad PD by operating a pair of arms 3, an eccentric shaft 16 disposed on one of a pair of base end shafts 12, extended in a vertical direction Z, and having a center axis O2 extended along a center axis O1 of the base end shaft 12, an eccentric cam link 5 supported by the eccentric shaft 16 and extended in a longitudinal direction Y, a piston 6 connected to the other end 5b of the eccentric cam link 5 rotatably about a center axis O3 extended in the vertical direction Z, and extended in a width direction X of a carriage, and a cylinder 7 disposed on a brake main body 2, supporting the piston 6 so that it can advance in a width direction X according to a brake command, and generating brake force while boosting through the pair of arms 3 by advancing of the piston 6.SELECTED DRAWING: Figure 1

    【課題】アームの初期位置が変動したとしても、ピストンのストローク量を確保し、十分なブレーキ力を得ることができるブレーキキャリパ装置を提供する。【解決手段】一対のアーム3を動作させることでブレーキパッドPDの初期位置を調整可能な隙間調整機構4と、一対の基端軸12のうちの一方に設けられ、上下方向Zに延び、かつ、基端軸12の中心軸線O1に沿って延びる中心軸線O2を有する偏心軸16と、偏心軸16に支持されて、前後方向Yに延びる偏心カムリンク5と、偏心カムリンク5の他端5bに上下方向Zに延びる中心軸線O3回りに回動可能に接続され、台車の幅方向Xに延びるピストン6と、ブレーキ本体2に設けられてピストン6をブレーキ指令に応じて幅方向Xに進出可能に支持するとともに、ピストン6の進出によって一対のアーム3を介して倍力してブレーキ力を発生させるシリンダ7と、を備えている。【選択図】図1
