車両用デイスクブレーキ装置。[Scope of claim for utility model registration] 1. Friction pads that slide on the brake disc,
The push rod engaged with the camshaft is pushed by a piston operated by pressure fluid supplied to the cylinder hole of the caliper, and mechanically rotates the camshaft fitted into the bearing of the caliper. In the disc brake device for a vehicle, the caliper is formed with a sub-cylinder hole that communicates with the cylinder hole, and a sub-piston that rotates the camshaft is placed in the sub-cylinder hole in a fluid-tight manner. A disc brake device for a vehicle, characterized in that it is movably inserted. 2 The friction pad that slides on the brake disc,
An adjusting mechanism that is pushed by a piston operated by a pressure fluid supplied to a cylinder hole of the caliper and includes an adjustment nut and an adjustment bolt screwed together with a multi-thread screw in the cylinder hole, and a sleeve piston are disposed, In a disc brake device for a vehicle, the friction pad is pushed by a push rod engaged with the camshaft and the sleeve piston by mechanically rotating a camshaft fitted into a bearing portion of the caliper, A sub-cylinder hole communicating with the cylinder hole is formed in the caliper, a sub-piston that rotates the camshaft is fitted into the sub-cylinder hole in a fluid-tight and movable manner, and a sub-piston is inserted into the sub-cylinder hole. A disc brake device for a vehicle, characterized in that it is provided with an elastic member that biases the brake in a counteracting direction. 3. The disc brake device for a vehicle according to claim 1 or 2, wherein the sub-cylinder hole is provided with a bleeder hole.
