A counterweight (8) is attached to the rear side of a revolving frame (6), and an engine (9) is mounted in a transverse direction in front of the counterweight (8). A heat exchanger (12) is located on the left side of the engine (9), and a left-hand side door (17) is located on the left side of the heat exchanger (12). An air cleaner (24) is accommodated in an air cleaner chamber (19) which is provided in a space enclosed by the counterweight, left-hand side door and heat exchanger. In this state, a casing (25) of the air cleaner has an opening portion (25A) to permit insertion and extraction of a filter element (26). Thus, at the time of a maintenance work for the air cleaner, one can draw out the filter element from the opening portion of the casing simply by opening the left-hand side door.

1. A construction machine, having a vehicular lower structure, an upper revolving structure swingably mounted on said vehicular lower structure, and a working mechanism provided at the front of said upper revolving structure; said upper revolving structure being comprised of a revolving frame serving as a support structure, a counterweight attached to a rear end of said revolving frame as a weight balance relative to said working mechanism, said counterweight having right and left ends formed in an arcuately curved shape toward forward direction, an engine transversely mounted on said revolving frame at a position in front of said counterweight, a heat exchanger located at one side of transverse direction of said engine to cool fluid, a side door comprised as a part of an exterior housing cover and openably and closably provided at a position on one side of said heat exchanger and on one of transverse sides of said counterweight, an air cleaner chamber substantially triangular shape enclosed by said counterweight, side door and heat exchanger, an air intake pipe having one end located in said air cleaner chamber and having the other end connected to an intake side of said engine, and an air cleaner located in said air cleaner chamber and provided at one end side of said air intake pipe to separate dust from the air by a filter element, characterized in that;said air cleaner having an opening portion to permit insertion and extraction of said filter element and said opening portion is disposed in such a way as to face said side door, anda midway portion of said air intake pipe being arrange to ride over a front portion of said heat exchanger and one end of said air intake pipe connecting to said air cleaner. 2. A construction machine as defined in claim 1, wherein said air cleaner is mounted in a transverse state, with said opening portion of said air cleaner in face to face relation with said side door. 3. A construction machine as defined in claim 1, wherein said air cleaner is located in a transverse state at least in a posture substantially parallel with the horizontal. 4. A construction machine as defined in claim 1, wherein said air cleaner is composed of a casing formed as a tubular container with said opening portion at a fore end thereof, and a filter element accommodated in said casing in a possible state of insertion and extraction through said opening portion. 5. A construction machine as defined in claim 4, wherein a box-like air inlet housing is attached to said casing of said air cleaner, in a space between said casing and said side door. 6. A construction machine as defined in claim 1, further comprising a cab built on a front side of said revolving frame positioned at one side of transverse direction, said heat exchanger being located on the rear side of said cab, and said air cleaner chamber being in the form of a substantially triangular space enclosed by said cab, said counterweight, said side door, and said heat exchanger. 7. A construction machine as defined in claim 6, wherein said heat exchanger is located in a position between said counterweight and said cab, and said air intake pipe has a midway portion en route, which midway portion being arranged to run along a rear panel of said cab and then ride over a front portion of said heat exchanger. 8. A construction machine as defined in claim 6, wherein said counterweight is composed of a center weight portion of a larger height and left and right side weight portions of a smaller height extending arcuately in rightward and leftward directions from said center weight portion, said side door is located at a position on one of said side weight portions of said counterweight and between a rear panel of said cab and said center weight portion, and said air cleaner is installed in said air cleaner chamber at a position behind said cab.
