    摘要: A cab for a construction machine includes an operator's seat within a cab box. Consoles are provided on the left and right sides of the operator's seat, respectively, and a switch box is provided on an outer side of an operating lever of the right console. Provided on the switch box are a control dial for variably controlling rotational speed of an engine, a working mode selector switch, and a vehicle drive mode selector switch. An operator who is seated on the operator's seat can manipulate the switches on the switch box by stretching a right arm toward the operating lever and by blind touch.

    摘要: Disclosed is a steel for machine structural use which is usable instead of Pb (lead) free-machining steel, has no adverse effect on environment, and can be stably machined. This steel for machine structural use comprises by mass carbon (C): 0.10 to 0.60%, silicon (Si): 0.05 to 1.0%, manganese (Mn): 0.3 to 2.0%, sulfur (S): 0.02 to 0.25%, aluminum (Al): 0.002 to 0.030%, and calcium (Ca): 0.0005 to 0.01%, with the balance consisting of iron (Fe) and unavoidable impurities, the steel satisfying Ca/Al ratio=0.1 to 1.0 in terms of % by mass ratio.
