In a device for guiding a linear movement of a linear power device (1) having a tube shaped housing (1') and within the housing a linearly moving drive element which over power transmitting means (3) is connected to a guiding slide (4), the device comprises, for fastening a guide rail (5) for the slide (4) onto the housing, two longitudinal elements constituting rail holders (6,7) which on the one hand are provided with gripping elements (16) on the housing, on the other hand with fastening means (9) for co-operation with the guide rail (5). Said rail holders (6, 7) are provided with longitudinal pivot surface (10.1,10.2) which are shaped so as to allow a mutual relative pivotal movement in directions crosswise with respect to the length extension of the rail holders. Each rail holder (6,7) comprises a longitudinal counter-pressure surface (11.1,12.1) for co-operation with pressing surfaces on the guide rail. Said pivot surfaces (10.1.10.2) and counter-pressure/pressing surface (at 11,12) in the mounted position of the device forming corners of a triangle or a quadrangle and said fastening means (9) constituting fastening screws (9) being distributed along the length of the guide rail, said screws being adapted such that when fastening of the device onto said housing (1') the shape of said triangle or quadrangle is deformed and thereby a clamping movement of said gripping elements (14,15) is obtained. <IMAGE> |
