Abstract
A construction machine including a maneuvering seat on which an operator sits, a guard cover for supporting the maneuvering seat thereon, and a control box arranged on one side of the maneuvering seat. The control box having a control valve and an operating lever for operating the control valve. The control box turning about a turning fulcrum so as to facilitate getting on and off when an operator gets on and off from the maneuvering seat. The construction machine further including hydraulic hoses which hang from the control valve and are pulled out of the control box. The hydraulic hoses having bent portions externally of the control box, the bent portions being displaced when the control box turns to absorb the up and down movement of the hydraulic hoses. Accordingly, the up and down movement of the hydraulic hoses caused when the control box is forced up is absorbed by bent portions provided externally of the control box.
