In a construction machine, an equipment room cover is formed with a maintenance hole, which has such a shape as to allow an air filter to pass, at a position on a rear side of the air filter mounted to a filter mounting portion of an air intake duct. A locking device of the filter mounting portion has a movable member movable between a locking position and a lock-releasing position. In the locking position, the movable member contacts with a rear surface of the air filter in a state that a front surface of the air filter is contacted with a contact member so that the air filter is sandwiched and held between the movable member and the contact member. In the lock-releasing position, the movable member is moved away from the rear surface of the air filter for allowing movement of the air filter toward the rear side.

Construction machine

A highest footboard of steps serving as an up and down passage provided on the laterally opposite side to a cabin in an upper rotating body is located at a higher position than a highest footboard of steps of standard specifications. In a space which is height difference between the highest footboards, a fuel supply unit is installed. The steps are supported by a step supporting portion of a bracket provided in a device chamber through the fuel supply unit.

On the laterally opposite side of an upper frame constructing an upper rotating body to a cabin, are installed devices in a state that a pin insertion and removal space sufficient for inserting and removing a boom foot pin in the axial direction is ensured, and in a bracket provided in the pin insertion and removal space, is provided a pin guide in a square tube shape for guiding the boom foot pin in the insertion and removal direction.
