Claims

[Scope of utility model registration request]

A cylinder body having a cylinder hole formed therein, a piston slidably inserted into the cylinder hole, a brake pad that is pressed against a brake disk by the piston, and a brake pad that is pivotally supported by the cylinder body and has one end extending outside the cylinder body. a protruding shaft; a toggle disposed between the shaft and the piston for converting rotational motion of the shaft into linear motion; a strut for transmitting the movement of the toggle to the piston; and a strut attached to the protruding portion of the shaft for parking. A lever to which a wire is connected, a stopper provided on the cylinder body and having an enlarged portion, and a torsion coil spring tensioned between the stopper and the lever to bias the lever in a non-operating direction. The torsion coil spring has one hook portion that engages with the stopper between the enlarged portion of the stopper and the cylinder body, a coil portion that is externally fitted on the shaft, and engages with the lever. In the disc brake with a parking mechanism, the engagement part that engages with the lever and prevents the lever from rotating when the lever rotates beyond a predetermined position is attached to the one hook. A disc brake with a parking mechanism formed in the part.
