ABSTRACT:
A sealing cap for cylindrical parts such as a bolt guide of a spot-type disc brake, comprises an elastic pleated bellows (15), one end portion of which is fastened to the periphery of a first cylindrical part, while the other end portion thereof is secured to the periphery of a second cylindrical part. A rigid reinforcing and retaining member (16, 17) is provided on at least one of said end portions (13, 14), with each reinforcing and retaining member being arranged with at least part of its radial extension on the same radius. To create a sealing cap which affords ease of manufacture and assembly, at least one of the reinforcing and retaining members (16, 14, 58) is provided of substantially U-shaped configuration when viewed in axial cross-section, thus forming first and second wall portions (26, 27; 47, 67; 59) as well as a base portion interconnecting said wall portions. The wall portions embracing the end portion (14; 38) of the sealing cap (12; 36) in a bracket-like manner, and at least one of the wall portions (26; 47; 59) is arranged in an annular groove (26; 53) in the corresponding cylindrical part.
