Construction machine having a sheathing material

摘要

Disclosed is a sheathing material for a construction machine and a method for producing the same, in which lightweighting can be attained without using a reinforcing member, and which is not greatly flexed even if a load is applied. The sheathing material for a construction machine which is lightweighted and has a flexure rigidify is obtained by molding a resined shell (1d) having a hollow construction by rotational molding, filling a resin foamed body (1e) such as a hard polyurethane foam within the resined shell (1d) to set it, thereby providing a sandwiching construction, and adjusting filling density of the resin foamed body (1e).
