Claim:
Arrangement in a tube ( 11 ) for an engine powered tool for support of a drive shaft extending inside the tube ( 11 ), characterised in that the drive shaft is surrounded by a tube shaped section ( 15 ) acting as a shaft support ( 14 ) for the drive shaft, said tube shaped section ( 15 ) is constituted by a number of generally symmetrical discontinuous sections ( 19 ) moveable relative to each other and each being provided with at least one rib ( 16 ) each having a tip end ( 30 ) for support of the tube shaped section ( 15 ) inside the tube ( 11 ), the at least one rib ( 16 ) being generally symmetrical and extending in a radial direction outwards from the tube shaped section ( 15 ) towards contact with the tube ( 11 ), and flexible parts ( 17 ) placed between the discontinuous sections ( 19 ) to absorb movements between the discontinuous sections ( 19 ), each of said discontinuous sections ( 19 ) being attached to an adjacent discontinuous section ( 19 ) by way of a flexible part ( 17 ), the discontinuous sections being biased away from each other by the flexible parts ( 17 ) such that the tip end ( 30 ) of the at least one rib ( 16 ) abuts the tube ( 11 ).
