Document Type and Number:
Japanese Patent JP2012137029
Kind Code:

Abstract:

To provide a construction machine capable of preventing an intermediate shroud formed of an elastic material from being worn or damaged, of securing cooling efficiency, and of improving reliability.

An intermediate shroud 25 arranged between a heat exchanger-side shroud 23 and a fan-side shroud 24 has a structure including an attachment part 26 attached to the heat exchanger-side shroud 23, a contact part 29 contacting an outer peripheral surface 24A of the fan-side shroud 24 throughout the entire circumference thereof, and an inner projection part 30 formed in the vicinity of the contact part 29. Thereby, when the fan-side shroud 24 tilts with respect to the heat exchanger-side shroud 23, the outer peripheral surface 24A of the fan-side shroud 24 abuts on the inner projection part 30, and an end edge part 24E of the fan-side shroud 24 and the intermediate shroud 25 can be prevented from coming into contact with each other.
