发明名称 HYDRAULIC EXCAVATOR
摘要 A hydraulic excavator includes a cab and a work implement arranged on one lateral side of the cab. The cab includes an operator's seat, front pillars, a roof portion, first and second guide rails, a front window, a monitor device, a monitor, and a support member. The monitor is supported on a first pillar above the monitor device and has a second display screen larger than a first display screen. The support member supports the monitor so as to be movable between an interference position interfering with a movement region where the front window moves between a closed state and an opened state of an opening, and a non-interference position with no interference. Accordingly, a hydraulic excavator can be obtained in which a large-sized monitor can be arranged on a front side of the cab without interference with a movable front window.
