Abstract: The present invention provides an electronic device support mechanism that ensures heat dissipation capability for an electronic device mounted on a construction machine, and a construction machine including the electronic device support mechanism. The electronic device support mechanism of the present invention includes a housing 21 that is disposed with a space adjacent to a lower structural object on a back side of a seat in an operating cab 2 of a construction machine and in which an electronic device is housed, and one or more side wall parts 29 of the housing 21 and a lower wall part 22 of the housing 21 are each provided with one selected from among a vent 43 and a fan 42.

Abstract: A display device 20 includes: a hinge 91; a first monitor device 21 including a first front surface 22; and a second monitor device 31 including a second front surface 32. Parallel planes from a virtual second front surface on a rear side by predetermined distances at a first angle a to a third angle c between the first front surface 22 and the virtual second front surface are defined as first to third virtual planes E to G. A rotation axis X1 of the hinge 91 is disposed on anyone of these three virtual planes or inside a space formed by the three virtual planes in a view in a direction parallel to the rotation axis X1, and the second front surface 32 is disposed at a position away from the rotation axis X1 on a front side of the second monitor device 31 by a predetermined distance.
