Japanese Patent Application Laid-Open No. 8-100444 (pages 2 to 3, drawings 1 to 2)

In the case of the hydraulic excavator, the tool box can be installed inside the step by using a step which is easy to draw out when the tool is used, for example, a step that is installed around the upper swing structure as described in the prior art, or It is common practice to form a window on a part of the circumferential wall of the upper swing structure so that a tool box can be installed inside the upper swing structure.

However, in the hydraulic excavator so that the entire circumferential turning radius of the upper turning body is accommodated within the left and right widths of the lower turning body, steps cannot be provided around the circumferential wall of the upper turning body beyond the turning radius of the upper turning body. It is difficult to provide a step inside the swing radius of the upper swing structure because it restricts the dedicated space of the mounting fixture. In addition, even if a window is formed on the circumferential wall of the upper swing structure to make a tool box installation space inside the swing structure, a sufficient size of space cannot be secured, so a tool box having a sufficient volume cannot be secured. have.

In addition, even in a hydraulic excavator in which the rear turning radius of the upper swinging body is accommodated within the left and right widths of the lower traveling body, a box-shaped step is provided at the front corner side of the upper swinging body so that the tool box is installed at the upper swinging body. It is difficult to implement because the work machine swing bracket installed at the front end interferes, and even if a tool box installation space can be made inside the swing structure by forming a window on the circumferential wall of the upper swing structure, sufficient space can be secured. Therefore, there is a problem of becoming a small storage tool box.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tool storage device of a hydraulic excavator that allows a large tool box to be installed inside the upper swing structure without changing the layout of the existing payload inside the upper swing structure. do.
