Abstract

The pulley has a central fastening bolt (4) which is covered by a cap (6). A tool can be connected to the bolt through a central bore (9) in the cap, and can be prevented from falling out by axially acting shape-mating elements.The head of the bolt may be arranged so that a cylindrical surface (10) is presented in the bore, and may also have a flange section (11) which engages behind the bore. The bolt may have a head with a socket for a hexagonal key, which can be inserted through the bore so that the head of the bolt does not have to project from the cap
