Abstract
A left console device (11) disposed on an entrance (8A)-side of a cab (8) is provided with a gate lock device (19). The gate lock device (19) includes a gate lock lever (20) which has an operating part (20C) to be operated by an operator and is rotationally displaced between a lock position and an unlock position, and a spring member (22) which urges the gate lock lever (20) toward the lock position or the unlock position. The spring member (22) is configured to urge the gate lock lever (20) toward the unlock position when the operating part (20C) of the gate lock lever (20) is in a height position lower than an upper surface (16C) of the left console device (11) (an upper cover (16)) and urges the gate lock lever (20) toward the lock position when the operating part (20C) of the gate lock lever (20) is in a height position higher than the upper surface (16C) of the left console device (11).
