Abstract

A rolling boot comprises a first fastening region for fastening the boot to a joint casing, a second fastening region for fastening the boot to a shaft, and a fold region between the first and the second fastening region with a first fold near to the first fastening region and a second fold near to the second fastening region. The boot further comprises, between the first fastening region and the first fold, a first transition region comprising a first flange neighboring the first fastening region with a bottom. A ratio between a first minimal diameter D1, defined by the bottom of the first flange of the first transition region, and a second maximal diameter D2, defined by the first fold, where both are viewed in a longitudinal section direction along the main axis, is between approximately 1:1.01 to approximately 1:1.25.
