Abstract: A cab of a construction machine enables an operator sitting on an operation seat to easily perform visual confirmation and operation of a portable communication terminal. The cab includes a floor plate, an operation seat positionally adjustable in the front-rear direction to the floor plate, and a control box disposed sideward of the operation seat. The control box includes a box body, and an operation lever protruding upward beyond the upper surface of a front part of the box body to receive an operation by the operator sitting on the operation seat. The box body includes a portable communication terminal holding portion that receives insertion of a portable communication terminal at a position frontward of the operation lever and holds the inserted portable communication terminal while exposing at least a part of the portable communication terminal above the box body.

Abstract: A seat stand includes a seat support section including an installation plate portion having an upper surface on which a seat is provided and an left control box support section extending from a seat support section to the left side of the seat and supporting a left control box. The left control box support section includes an extension portion extending sideward from the installation plate portion and including an upper surface on which the left control box is supported. A arranging space is provided under the extension portion in such a manner that a connection line extending from the left control box supported on the extension portion is arranged through the arranging space. A cutout portion, formed in the extension portion, penetrates the extension portion in a vertical direction and is open sideward.

Abstract: Provided is a construction machine where a pilot hose is easily routed. The construction machine includes a seat stand, an operator's seat provided on the seat stand, a remote control valve provided just above a front end of the seat stand at least one of right and left sides of the operator's seat; a hydraulic valve; and a pilot hose interconnecting the remote control valve and the hydraulic valve. The seat stand has an upper surface including a specific surface located beneath the remote control valve and a reference surface on which the operator's seat is installed. A step is provided between the specific surface and the reference surface to make the specific surface be lower than the reference surface, thus enlarging a space for routing the pilot hose beneath the remote control valve.

Abstract: A floor panel is formed with an opening for mounting a pedal device. The opening permits a remote control valve to penetrate through the floor panel. The opening has an insertion region configured to allow the joint, the hydraulic hose and a lower portion of a valve body to be inserted thereinto from above the floor panel, and an arrangement region located in side-by-side relation to the insertion region in a second direction and configured to allow the valve body to be arranged therein while being fixed to the floor panel. In top plan view, a length of the opening in the second direction is less than a length of the opening in the first direction, and a length of the arrangement region in the first direction is less than a length of the insertion region in the first direction.
