An extendable arm structure (10) includes: an upper extendable arm (11) and a lower extendable arm (12) which extend parallel in a same direction; and a vertical coupling member that couples the upper and lower extendable arms. Each of the extendable arms (11, 12) includes a plurality of X-shaped cross units each formed by pivotally coupling two rigid members (11a, 11b, 12a, 12b) via a middle coupling shaft (11c, 12c), and two end coupling shafts (11d, 12d) that pivotally couple ends of adjacent ones of the cross units. The extendable arm structure (10) further includes: a planar member (13) that closes, in a planar fashion, a space between the rigid member (11a, 11b) of the upper extendable arm and the rigid member (12a, 12b) of the lower extendable arm which extends parallel to the rigid member of the upper extendable arm in a same direction.
