Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation section structure of an aerial work vehicle. 2. Description of the Related Art An aerial work vehicle is configured such that a work table is mounted on a dolly provided with a traveling device via a telescopic mechanism so as to be movable up and down, and the traveling operation of the dolly and the descent of the work table are performed. Various operation operations such as operation of the expansion and contraction mechanism and operation of other mechanisms are configured to be performed in the operation box section provided on the workbench. In general, the dash panel portion of the operation box is covered with an opening / closing lid, and the outside of the dash panel portion is guarded by being surrounded by a handrail rod (for example, a real open shovel). 59-18799). [0003] By the way, the operation box section of the conventional aerial work vehicle is, as can be confirmed from the above-mentioned literature, one of the operation tools provided on the dash panel section of the operation box. Some of them are in a state of protruding largely upward from the upper surface of the handrail bar when the opening / closing lid is opened, so that other objects such as materials handled by the operator on the workbench protrude from the handrail bar. There has been a problem that a dolly, a workbench, and other operation mechanisms may unexpectedly operate by accidentally touching the operation tool, which may cause danger. In the conventional operation box portion, are working in as one likes the lid is opened, cement or paint, the dust is something like not read the operation display of the same parts depends on the dash portion, the driving operation There are also problems to be troubled.Furthermore, in the conventional one, it is easy to assemble and connect the interlocking tools for linking the operation unit of the traveling device, the expansion and contraction mechanism, and other electric components with the operation box. However, there was a problem that it was difficult to perform manufacturing assembly and maintenance work. Therefore, the present invention has been made with the object of providing an operation section structure of an aerial work vehicle that solves these various problems.
