Claims

[Claims for Utility Model Registration] A housing, a disc rotor rotatably held in the housing and rotated by a drive device, and a disc rotor provided on both sides of a part of the periphery of the disc rotor and held in the housing at a variable relative interval. a set of two back members, each holding a lining held on opposing surfaces of the back member and sandwiching the disk rotor; a biasing member that urges the back member toward each other; A pair of outer engaging members provided on the back member and having a pair of outer engaging surfaces facing each other; and a pair of outer engaging members provided between the pair of outer engaging members and rotated by an operating shaft, A disc brake device comprising: a cam-shaped inner engaging member having a pair of inner engaging surfaces that come into contact with the outer engaging surface of the engaging member, the pair of outer engaging surfaces having a relative facing distance. an inclined facing surface that increases continuously from one side to the other, and a surface between at least one of the outer engaging member and the inner engaging member and the back member, which is arranged so that the back member moves close to the back member. An adjustment member is provided that is interlocked with the inner engaging member and the outer engaging member to relatively move the relative positions of the inner engaging member and the outer engaging member in a direction in which the relative facing distance increases, and compensates for proximity displacement of the back member due to wear of the lining. A disc brake device configured to.
