To obtain a support structure of a clamp member in which the axial displacement of the clamp member with respect to a caliper can be smoothly performed, related to a disc brake device having both two functions of a service brake and a parking brake.SOLUTION: A guide cylinder 22 is arranged inside an inner body part 14 constituting a caliper 8 in an axial direction. The guide cylinder 22 extends to the inside of the axial direction from an opening edge of a turn-side inner cylinder 19a in which a nut 71 constituting a thrust generation mechanism 42 is arranged. The guide cylinder 22 is fit into an accommodation hole 50 of a clamp base part 44 arranged inside the inner body 14 in the axial direction out of the clamp member 41 so as to be relatively movable with respect to the axial direction, and a first guide part 53 for supporting the clamp member 41 so as to be displaceable with respect to the caliper 8 in the axial direction is constituted.SELECTED DRAWING: Figure 8

    【課題】サービスブレーキとパーキングブレーキとの2つの機能をあわせ持つディスクブレーキ装置に関して、キャリパに対するクランプ部材の軸方向変位が円滑に行える、クランプ部材の支持構造を実現する。【解決手段】キャリパ8を構成するインナボディ部14の軸方向内側部に、ガイド筒22を設ける。ガイド筒22は、推力発生機構42を構成するナット71がその内側に配置された回入側インナシリンダ19aの開口縁部から軸方向内側に伸長している。このようなガイド筒22を、クランプ部材41のうちで、インナボディ部14の軸方向内側に配置されたクランプ基部44の収納孔50の内側に、軸方向に関する相対移動を可能に嵌合し、クランプ部材41をキャリパ8に対し軸方向の変位を可能に支持する第一ガイド部53を構成する。【選択図】図8
