Abstract
A pushing-out apparatus for an extendible mast includes a mast storing unit, a mast pushing-out unit and a mast pushing-out driving unit. The storing unit stores an extendible mast including stages of foldable trusses in a state that the stages are folded. The pushing-out unit is stored in the storing unit around the stage-folded mast stored in the storing unit. The driving unit moves the pushing-out unit to a projecting position in an outside of the storing unit while the stages of the mast are folded, sequentially extend out the folded stages of the mast stored in the storing unit by the pushing-out unit from the storing unit and push out the extended stages from the pushing-out unit of the projecting position in a side of the pushing-out unit opposing to the storing unit.
