Abstract: To provide a cab in which opening and closing of a door is hardly inhibited even if a cab frame or a door is deformed. A cab comprises a cab main body having a cab frame and a doorway formed in the cab frame. The cab comprises a door that opens and closes the doorway of the cab main body. The door is installed to the cab main body so as to be opposed to the side surface of the cab frame in a closed state of the doorway.

Abstract: A work machine comprises a main body, a cab riser, and a shaft. The cab riser includes a cab and a frame, the cab being uprightly positioned on the work machine in a first position, and being tilted forward in a second position, and the frame comprising a first plate to contact a second plate provided on the main body in the first position. The cab riser is rotatable about the shaft in clockwise and counterclockwise directions to and from the first position and the second position. The first plate and the second plate can be clamped together by a clamping assembly in the first position, the clamping assembly including one or more clamps to clamp the first plate and the second plate, and the clamping assembly is mounted on the main body.

Abstract: A console upturnably provided adjacent to an access area for gaining access to a seat installed in a work machine is provided with a release lever, to disengage a console securing locking portion and enabling the console to be upturned. The console has a hydraulic locking lever. Shifting the hydraulic locking lever to an opening position unblocks the access area, and performs a locking function to disable operation of the work machine; shifting the hydraulic locking lever to a blocking position to block the access area performs an unlocking function, thereby enabling operation of the work machine. Provided in relation to the release lever is a lever operation restraining mechanism that disengages the release lever and enables the console to be upturned when the hydraulic locking lever is in the opening position, and prevent upturning operation when the hydraulic locking lever is in the blocking position.
