PARTITION WALL

A partition wall section (1) intended to be fitted between a floor (5) and a ceiling (4) of a cargo space (3), comprising a wall panel (10), a floor contacting portion (20) displaceable between a contracted position and an expanded position, and a ceiling contacting portion (40). When the floor contacting portion (20) is brought into its expanded position, said ceiling contacting portion (40) is brought into contact with the ceiling (4). The wall section (1) comprises a plurality of rolling members (30) arranged along said first edge. In the contracted position of the floor contacting portion (20), the wall section (1) is rollable on said rolling members (30). In the expanded position, the floor contacting portion (20) projects beyond said rolling members (30), so as to enable the wall section (1) to be supported by said floor contacting portion (20), when in a substantially upright position.
