Abstract
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 rigidity 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.
