PROBLEM TO BE SOLVED: To provide a door lock device of construction equipment, which is simple in structure, can positively lock a door in a door opening position, and facilitates cancellation of a door locking state. SOLUTION: The door lock device of the construction equipment functions to openably support the door with respect to an opening section of an engine room. A lever 22 of the door lock device is supported on a bracket 21 on an inner surface of the door, via a proximal bent portion 22a in a manner rotatable about an axial line L-L in parallel with a shaft and in a manner movable in the axial line. Then a guide member 25 is arranged at a peripheral edge of the engine room opening section, and the guide member 25 has a guide surface 26b arranged thereon, for movably supporting a proximal bent portion 22b of the lever 22 when the door is opened/closed, and a guide groove 27 formed therein, for guiding movement of the proximal bent portion 22b of the lever 22. Therefore the guide surface 26b has formed thereon an engaging surface 26a for engaging with the distal bent portion 22b of the lever 22 and locking the door in the door opening position, by moving the lever 22 in the axial direction L-L when the door is opened.
