To make it possible to perform attachment/detachment without performance of complicated operation of attaching and detaching a temporary support member in a telescopic cylinder assembly for a telescopic boom.SOLUTION: A telescopic cylinder assembly 90 comprises integrally: a telescopic cylinder 50; a second base end sheave assembly 80 which is slidably provided along a cylinder tube 52; a cylinder base end assembly 86 which is fixed to a base end part 52b of the cylinder tube 52; and wiring 41 or the like. The second base end sheave assembly 80 has a cylinder slide member 81 which slides along the cylinder tube 52 and is fixed to a base end part 13a of a third-stage boom, and a second base end sheave 73 around which the wiring 41 or the like is routed. The cylinder base end assembly 86 has a base member 87 which is fixed to the base end part 52b of the cylinder tube 52, and a cylinder fixing sheave 53 around which the wiring 41 or the like is routed.SELECTED DRAWING: Figure 3
