PROBLEM TO BE SOLVED: To reduce the number of components including a support bracing supporting the front part of a cooler, a partition wall, and related components, and combined costs to improve assembly workability. SOLUTION: The partition wall 24 partitioning an engine room 9 is disposed horizontally on the left at the rear of an upper frame 8 composing an upper swiveling body, and an engine 10 and the cooler 13 are housed in the engine room 9. In this configuration, the front support bracing 25 supporting the front part of the cooler 13 is connected to the back face of the partition wall 24 in a face-to-face contact. As a result, the support bracing 25 serves also as a bracing for the partition wall 24, the partition wall 24 serves also as a stay for preventing the side swing of the support bracing 25, and a sealing material filling a gap between the support bracing 25 and the partition wall 24 can be dispensed with.
