PROBLEM TO BE SOLVED: To easily avoid an obstacle even when the obstacle is disposed under a fire wall, improve the assembly workability of the fire wall, and reduce manufacturing costs.SOLUTION: A fire wall 23 that partitions a space 20 in an engine enclosure 18 into an engine compartment 29 in which an engine 8 and an exhaust gas treatment device 14 are installed and a pump chamber 30 in which a hydraulic pump 12 is installed. The fire wall 23 consists of an upper shield member 24 that is positioned higher than the hydraulic pump 12 and extends in the width direction orthogonal to the longitudinal direction of the engine 8 and a pair of lower shield members 26 that are attached to the lower portion of the upper shield member 24 so that they sandwich the hydraulic pump 12 and extend downward from the upper shield member 24. In addition, each of the lower shield members 26 is formed into a plate shape by using a rubber material having flexibility and heat resistance. |
