Abstract: A work vehicle which can provide more accommodation space for articles on a vehicular body frame is provided. A rear cab mount on which a cab of a hydraulic excavator is mounted is mounted on a revolving frame and forms a hollow rear under-mount space. An opening portion is formed at a position corresponding to a side of the rear under-mount space in an exterior cover which laterally covers the revolving frame. A rear door body can open and close the opening portion. The rear door body opens the rear under-mount space to an external space with the opening portion being opened.

Abstract: A first plate material is set on a work stage. The first plate material includes first components commonly connected to a first connection member. A second plate material is subsequently set on the work stage. The second plate material includes second components commonly connected to a second connection member. The second components are superposed on the corresponding first components. The first components as well as the second components can be handled as a one-piece component. It leads to an improved productivity. Heat surfaces of a heat block contact the second components. The connection members are prevented from thermal expansion. The constant intervals are reliably maintained between the adjacent first components and the adjacent second components.

Abstract: A display bonding device includes a stage configured to place an adhesive tape and an adherend thereon, a pressure head configured to press the adhesive tape onto the adherend with a pressure surface having a tapered shape or a curved shape which is tilted with respect to the stage, and a movement mechanism configured to move the pressure head toward the adhesive tape through a pressure rod which is coupled to the pressure head. The pressure head is configured to rotate around the pressure rod.
