PROBLEM TO BE SOLVED: To provide a disc brake device having a compact parallelism maintenance control mechanism.SOLUTION: A disc brake device 11 comprises an actuator 17 for expanding one oscillation end 33 of a pair of brake arms 15 which are pivoted to a caliper body 25 so as to be oscillatory, and a parallelism maintenance control mechanism 23 for pressing a lining face 41 of a pad 39 held at a pad holding member 19 which is rotatably pivoted to the other oscillation end 35 of the brake arm 15 to a disc rotor in parallel therewith. The parallelism maintenance control mechanism 23 comprises: a pressing plate 49 which abuts on the pad holding member 19; a link arm 47 having a fixed shaft which is protrusively arranged at a side face of the disc rotor from the caliper body 25 in parallel therewith, a moving shaft which is arranged in parallel with the fixed shaft, and pivots the pressing plate 49, joint members which connect the fixed shaft and the moving shaft in parallel, and a connecting shaft 63 which pivots the joint members; and a spring member 45 which presses the pressing plate 49 to the pad holding member 19.SELECTED DRAWING: Figure 3

    【課題】コンパクトな平行維持制御機構を備えたディスクブレーキ装置を提供する。【解決手段】ディスクブレーキ装置11は、キャリパボディ25に揺動可能に軸支された一対のブレーキアーム15の一方の揺動端33を拡開作動するアクチュエータ17と、ブレーキアーム15の他方の揺動端35に旋回自在に軸支されたパッド保持部材19に保持されたパッド39のライニング面41をディスクロータに平行に押圧する平行維持制御機構23と、を備える。平行維持制御機構23が、パッド保持部材19に当接する押圧板49と、キャリパボディ25からディスクロータの側面に平行に突設される固定軸と、固定軸と平行に配設されて押圧板49を軸支する移動軸と、固定軸と移動軸とを平行に連結する関節部材と、関節部材同士を軸支する連結軸63と、を有するリンクアーム47と、押圧板49をパッド保持部材19に押付けるばね部材45と、を備える。【選択図】図3
