<p>Attachment means for arresting a member (11) having a cylindrical bops (11a) on a shaft (10), and with an annular space (13) between said member and shaft, a pair of elements (15) having co-operating tapers inserted in the space and intended at mutual displacement to increase or reduce a clamping force between member and shaft, the elements comprise a first sleeve member (15a) with smooth inner surface enclosing the shaft (10), and a second sleeve member (15') with smooth outer surface for engaging the bore (11a) of the member (11), said second sleeve member (15') enclosing the first sleeve member (15a), whereby the first and second sleeve members (15a, 15') in their surfaces facing each other have saw-tooth-shaped axially tapering sections (15c, 15e), the second sleeve member (15') with one end edge abutting a stop (12) in the member (11), and the first sleeve member (15a) projecting outside the opposite end edge of the second sleeve member (15'), for being readily accessible for an external pushing force. <IMAGE></p> |
