では、上記の問題点を解決できる上下開閉式のカバ−の
開時保持装置を提供することを目的とする。When using a construction / working machine such as a hydraulic excavator, it is not always necessary to fully open the cover when inspecting and repairing the equipment arranged in the guard. It is often made in half-open condition.
However, in the prior art, since the means for holding the cover in the half-opened state is not provided, the cover must be supported at this time, which is inconvenient and difficult to perform. SUMMARY OF THE INVENTION It is an object of the present invention to provide an open / close cover holding device for an open / close type that can solve the above problems.

を係止させる複数個の保持部を段階的に設けた。In order to achieve the above-mentioned object, in the vertical opening / closing type holding device of the present invention, a body is formed by pivotally attaching a stay to the inner surface of the vertical opening / closing type cover. When the cover is opened, the frame is attached to the frame.
A plurality of holding portions for locking the are provided in stages.

持させる凹状係止部を穿設した。In the above-mentioned stay, both ends of a slender rod-like member are bent to form respective engaging portions, and one of the engaging portions is rocked on a locking metal fitting fixed to the inner surface of the cover. The holding portion is provided with a guide groove for guiding the other engaging portion of the station on a thin plate member standing upright so as to be perpendicular to the opening / closing center axis of the cover. A hole is formed, and a concave locking portion for holding the engaging portion of the above-mentioned station is formed at the inner edge of the guide groove.

い。In the upper / lower cover type holding device constructed as described above, one end of the station is pivotally attached to the inner surface of the cover,
The other end is configured to be loosely inserted into a guide groove formed in the frame for guiding. The guide groove rises substantially vertically from the lower side to the upper side, and forms a smooth curved groove portion that gradually extends toward the inside of the body from the middle, and the concave groove is formed at least at two places on the lower edge of the curved groove portion. A joint is drilled. Therefore, when the cover is opened upward, the engaging portion of the station is guided by the guide groove and moves upward, and then moves in the curved groove portion. Here, since the cover-side pivotal portion of the steer gradually faces toward the inside of the fuselage, the steer gradually increases the inclination, and its own weight generates a downward rotational force about the pivotal portion, When reaching the concave engaging portion, the engaging portion of the station falls onto the concave engaging portion and is securely held by the U-shaped holding portion. Further, even if the cover is opened and held by the strong wind, and the force for opening the cover acts, the engaging portion of the station abuts on the R-shaped stopper portion above the concave engaging portion to prevent further floating. It blocks and the cover does not inadvertently open or close.
