1. A disk brake comprising a brake caliper and an application device arranged therein for applying force to the brake pads of the disk brake, wherein a component of the application device is a brake lever which can be actuated by a force element, which brake lever is composed of a lever arm against which the force element is supported and an application shaft which is supported, on one side, against a pressure piece operating in the direction of the brake pads, and, on the other side, with the interposition of a shell, against a channel arranged on the inside of the brake caliper, wherein the curvature of the shell is complementary to the curvature of the channel, characterized in that an opening of a bore is located in the channel, in that a passage produced by deformation of material of the shell is formed on the shell, facing the channel, which passage leads to a collar that extends into the bore to produce a positive fit between the shell and the channel, and in that a shaped element is arranged in the passage, the outer diameter of which shaped element is equal or nearly equal to the inner diameter of the passage,
wherein a blind bore serves as the bore,
wherein the length of the bore has a greater depth than the sum of the passage and of the shaped element protruding from the passage, wherein the bore has a depth equal to or greater than 1.2 times the axial extension of the shaped element.
