PROBLEM TO BE SOLVED: To well perform cleaning at an end part of a cooler.SOLUTION: A cooling unit 20 is fitted on a surface on a housing chamber 15 side of a cooler cover 25 in which cover plates 29, 26, and 27 are arranged in such a manner as to cover three peripheral surfaces of a cooler 21, namely an upper surface, a front side, and a far side, to allow a fan case 35 that houses a cooling fan 22 to be opened/closed around a far edge side. On the cover plate 26 constituting the front side surface of the cooler cover 25, a through hole 40 is opened which functions to allow cleaning water to run. On the side edge on the housing chamber 15 side of the cover plate 27 constituting a far side surface of the cooler cover 25, a bending part 28A is formed which covers the far edge of the front surface of the cooler 21. A lengthy slit 42 which functions to allow cleaning water to run is opened at the bending part 28A. |
