An engine cover comprises a top surface part covering an engine from above and a rear surface part hanging down from a rear end of the top surface part and making contact with a top surface of a counterweight. A lock device is provided between the engine cover and the counterweight for locking the engine cover to the counterweight. The rear surface part of the engine cover is recessed toward the engine side to provide a lock device-accommodating recessed portion for accommodating the lock device. A camera opening is provided in an upper position of the lock device-accommodating recessed portion, and the rear-view camera is mounted to an inner surface side of the engine cover in a position corresponding to the camera opening.

A striker provided on a rear surface part of an engine cover is mounted on the rear surface part by using nuts from an inner surface. In a counterweight, a bracket is mounted on a top surface of a center weight portion by using bracket bolts, and a latch is mounted on a latch mounting surface of the bracket by using latch bolts. In this state, a hiding member is mounted on a hiding member mounting surface of the bracket by using hiding member bolts. At this time, the hiding member can cover and hide the bracket bolts and the latch bolts. Further, at the time the engine cover is closed, the bolts can be hidden.
