Claims

[Scope of utility model registration request]

A caliper device is attached to the distal end side of a caliper bracket whose base end is rotatably supported on the vehicle body, and the piston is pushed by the caliper bracket which rotates due to the braking torque acting on the caliper device during braking. In a disc brake device for a vehicle in which an operating hydraulic pressure generating device is attached to a fixed part on the vehicle body side in the peripheral direction of the brake disc, a water draining portion close to the vehicle body side is provided on the side that becomes the lower surface when the hydraulic pressure generating device is attached. and a water guiding surface that is inclined diagonally downward so that the draining portion side is lower.
