    Abstract: A hydraulic excavator as a work vehicle includes: a revolving frame; and a cab. The cab includes: a floor member that faces the revolving frame, with a gap therebetween; a support base provided on the floor member and supporting an operator's seat; a pillar member connected to a left end of the floor member; and a reinforcing member connected to the pillar member and the support base. The hydraulic excavator further includes a restriction member provided in the gap and protruding from the floor member toward the revolving frame. The restriction member has a protrusion length shorter than a length of the gap in an up-down direction, and is provided below the support base.

    Abstract: An operator's cab includes an operator's seat provided on a floor surface, a control lever that is provided laterally to the operator's seat and is operated at least toward the operator's seat, and an armrest that includes an upper surface and is provided laterally to the operator's seat in the rear of the control lever. A front portion of the upper surface is larger in width than a rear portion of the upper surface. The front portion of the upper surface includes an inclined portion. With the floor surface being defined as the reference, the inclined portion decreases in height toward the operator's seat.

    Abstract: 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.

    Abstract: A controller assembly includes a base plate, a bracket, and a first controller main body. The base plate includes a through hole and a frame having an upper surface and a lower surface and surrounding the through hole. The bracket has first and second flange portions supported on the upper surface of the frame at positions opposite to each other over the through hole, first and second side portions coupled respectively to the first and second flange portions and passing through the though hole; and a bottom portion coupled to both of the first and second side portions on the side of the lower surface of the frame. The first controller main body is mounted on a bottom portion of the bracket. Accordingly, a controller assembly which can be readily assembled, a cab of a work implement, and a work machine can be obtained.
