Abstract
A construction machine includes a machine body, a walkwayformed on an upper surface of a lateral one side of the machine body, and a handrailconfigured to be height-variable by a fixed rail bodyprovided standing along the walkwayon the lateral one side on the upper surface of the machine body and a movable rail bodyattached rotatably to an upper end portion of the fixed rail bodyand foldable with respect to the fixed rail body. The fixed rail bodyhas a plurality of strutsthat each having a bent shape such that an upper portion is located more laterally outward than a lower portion. A mirroris attached to the strut. The mirroris disposed laterally outward than the lower portion of the strutand within a width of the machine body, and is disposed between the struts, below an upper end portion of the fixed rail body, and above a rotation tip portion of the movable rail bodyafter folded. In such a configuration, attaching the mirror to the foldable handrail to secure a lateral visibility neither result in interfering with folding of the handrail nor result in constituting obstacles to transporting, to the walkway, and to a cover opened/closed at maintenance.
