摘要

An adjustment end (11) of the inserted adjustment key (10) is set off-centre relative to the bearing socket (12) in which it fits. A removable security member fits into an indentation (15) in the bearing socket which holds the adjustment end of the key when the security member is removed. The adjustment end comprises several projections (16) corresponding in number to recesses (17) in the outer circumference of the bearing socket. The projections and recesses are evenly spaced from each other and can have a triangular cross-section with the tip facing inwards.
