RAINWATER INTRUSION PREVENTION STRUCTURE OF STATIONARY TYPE ENGINE WORKING MACHINE

PROBLEM TO BE SOLVED: To provide a method for a rainwater intrusion prevention structure capable of preventing intrusion of rainwater into a case body securely. SOLUTION: This structure of an exterior case body is a structure of the exterior case body 1 of the stationary type engine working machine. A side face of the exterior case body 1 is composed of a duct member 9 for communicating the inside and the outside of the exterior case body 1 mutually and a side plate 3a provided with an outer plate 15 forming an opening part 30 for exhaust having smaller opening area when compared with air passage cross sectional area (an opening part 34 for the duct member) by the duct member 9. A plate-like dam member 10 is erected in a bottom part of the duct member 9. A wind pressure type shutter 6 having larger opening area when compared with opening area of the opening part 30 for exhaust and communicating with the opening part 30 for exhaust is fixed on an outer face side of the side plate 3a. An opening part 32 for drainage for draining the water remaining in the inside of the wind pressure type shutter 6 and the water dammed up by the dam member 10 and remaining in the bottom part of the duct member 9 to the outside of the exterior case body 1 is formed in a connection part where the wind pressure type shutter 6 is fixed.
