The present invention provides a disk brake including a cam shaft rotatably mounted on a cylinder portion of a caliper and having an end portion protruding from the caliper, a brake lever fitted to the protruding end portion of the cam shaft so as to rotate the cam shaft when the brake lever rotates, and a helical return spring disposed above a fitting portion of the brake lever fitted to the cam shaft and fitted around the protruding end portion of the cam shaft. The spring has one end secured to the caliper. The brake lever is provided with a plate-like vertical portion extending in the axial direction of the cam shaft from the fitting portion toward a tip of the protruding end portion of the cam shaft. The vertical portion is provided at one side thereof with a bent lug to which the other end of the return spring is secured. The bent lug extends away from the cam shaft.
